The GCF is 21.
The LCM of 63 and 84 is 252.
Answer=7 because 7x9=63 7x12=84 7x18=126
No, 45 and 84 are not relatively prime.
Factors of 63: 1, 3, 7, 9, 21, 63.Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84.Factors of 126: 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126.GCF (63, 84, 126) = 21
The GCF is 21.
The GCF of 63, 84 and 126 is 21. The GCF of 6384 and 126 is 42.
The GCF is 21.
To find the greatest common factor (GCF) of 63, 84, and 126, we first need to list the factors of each number. The factors of 63 are 1, 3, 7, 9, 21, and 63. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84. The factors of 126 are 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, and 126. The GCF is the largest number that appears in all three lists, which in this case is 21.
21, 42, 63, 84, 105, 126 . . .
21, 42, 63, 84, 105, 126, 147, 168, 189, 210.
The GCF of 35, 63, and 84 is 7. The prime factorization of 35 is 5*7. The prime factorization of 63 is 3*3*7 The prime factorization of 84 is 2*2*3*7 The GCF of 35, 63, and 84 is thus 7.
