The list of prime factors of all numbers are
Prime factors of 870 are 2 x 3 x 5 x 29
Prime factors of 747 are 3 x 3 x 83
Prime factors of 180 are 2 x 2 x 3 x 3 x 5
Prime factors of 257 are 257
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 870, 747, 180, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(870, 747) = 216630
GCD(870, 747) = ( 870 x 747 ) / 216630
= 870 / 747
= 870
Step2:
LCM(3, 180) = 180
GCD(3, 180) = ( 3 x 180 ) / 180
= 3 / 180
= 3
Step3:
LCM(3, 257) = 771
GCD(3, 257) = ( 3 x 257 ) / 771
= 3 / 257
= 3
So, Greatest Common Divisor of 870, 747, 180, 257 is 1
