The Greatest Common Factor (GCF) is: 189
945 = 3³ × 5 × 7 4536 = 2³ × 3⁴ × 7 Thus, the greatest common factor is 3³ × 7 = 189.
840 and 945 have a GCF of 105. 945 and 1050 have a GCF of 105.
The GCF is 105.
The GCF is 315.
The GCF is 105.
The GCF is 105.
It is 105
The GCF is 105.
The GCF is 5.
The GCF is 105.
You need at least two numbers to find a GCF. If that's 9 and 45, the GCF is 9.
The GCF of 420, 735, and 945 is 105.The prime factorization of 420 is 2x2x3x5x7The prime factorization of 735 is 3x5x7x7The prime factorization of 945 is 3x3x3x5x7(1) List the prime factors of each number.(2) Multiply those factors all numbers in the set have in common. If there are no common prime factors, the GCF is 1. (Those factors are the ones in bold type.)As you can see the GCF is 3x5x7 or 105
