The list of prime factors of all numbers are
Prime factors of 870 are 2 x 3 x 5 x 29
Prime factors of 457 are 457
Prime factors of 456 are 2 x 2 x 2 x 3 x 19
Prime factors of 764 are 2 x 2 x 191
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 870, 457, 456, 764
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(870, 457) = 397590
GCD(870, 457) = ( 870 x 457 ) / 397590
= 870 / 457
= 870
Step2:
LCM(1, 456) = 456
GCD(1, 456) = ( 1 x 456 ) / 456
= 1 / 456
= 1
Step3:
LCM(1, 764) = 764
GCD(1, 764) = ( 1 x 764 ) / 764
= 1 / 764
= 1
So, Greatest Common Divisor of 870, 457, 456, 764 is 1
