Given numbers are 870, 158, 455, 668
The list of prime factors of all numbers are
Prime factors of 870 are 2 x 3 x 5 x 29
Prime factors of 158 are 2 x 79
Prime factors of 455 are 5 x 7 x 13
Prime factors of 668 are 2 x 2 x 167
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 870, 158, 455, 668
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(870, 158) = 68730
GCD(870, 158) = ( 870 x 158 ) / 68730
= 870 / 158
= 870
Step2:
LCM(2, 455) = 910
GCD(2, 455) = ( 2 x 455 ) / 910
= 2 / 455
= 2
Step3:
LCM(1, 668) = 668
GCD(1, 668) = ( 1 x 668 ) / 668
= 1 / 668
= 1
So, Greatest Common Divisor of 870, 158, 455, 668 is 1
