The GCF is 126.
The GCF is 14.
The GCF is 1.
You need at least two numbers to find a GCF. If that's 84, 126, 210 and 378, the GCF is 42.
126
gcf(126, 196, 378) = 14. Using prime factorization: 126 = 2 x 3² x 7 196 = 2² x 7² 378 = 2 x 3³ x 7 hcf = 2 x 7 = 14
The GCF is 18.
The GCF is 21.
The least common multiple (LCM) of 54 and 126 is 378.
The GCF of 63, 84 and 126 is 21. The GCF of 6384 and 126 is 42.
The GCF is 54.
The GCF is 54.
The GCF is 2.
