Web1. Find factors of the number. You don't have to know prime factorization to find the greatest common factor. Start by finding all the factors of the set you are comparing. [2] 2. … WebThe first method to find GCF for numbers 21 and 42 is to list all factors for both numbers and pick the highest common one: All factors of 21: 1, 3, 7, 21. All factors of 42: 1, 2, 3, 6, 7, …

What is the Greatest Common Factor of 42, 126, and 210?

WebThe GCF of 21 and 42 is 21. To calculate the greatest common factor of 21 and 42, we need to factor each number (factors of 21 = 1, 3, 7, 21; factors of 42 = 1, 2, 3, 6, 7, 14, … WebGCF of 42 and 90 is the divisor that we get when the remainder becomes 0 after doing long division repeatedly. Step 1: Divide 90 (larger number) by 42 (smaller number). Step 2: Since the remainder ≠ 0, we will divide the divisor of step 1 (42) by the remainder (6). Step 3: Repeat this process until the remainder = 0. daily rituals phoebe garnsworthy pdf

Find the GCF 42 , 70 , 84 Mathway

WebGreatest Common Factor We found the factors of 42, 126, 210 . The biggest common factor number is the GCF number. So the Greatest Common Factor 42, 126, 210 is 42. Therefore, GCF of numbers 42, 126, 210 is 42 Finding GCF of 42, 126, 210 using Prime Factorization Given Input Data is 42, 126, 210 WebThe Greatest Common Factor (GCF) for 21 and 42, notation CGF (21,42), is 21. Explanation: The factors of 21 are 1,3,7,21; The factors of 42 are 1,2,3,6,7,14,21,42. So, … WebFeb 17, 2024 · The correct answer is D: GCF is 2, and we reduce to \(\frac{8}{21}\). Let’s approach this problem by listing the prime factors of both the numerator and the denominator. \(16=2×2×2×2\) \(42=2×3×7\) Here we see that 2 is the only shared factor of 16 and 42 and is therefore their greatest common factor. daily ritual women\u0027s clothing amazon
