The list of prime factors of all numbers are
Prime factors of 646 are 2 x 17 x 19
Prime factors of 455 are 5 x 7 x 13
Prime factors of 500 are 2 x 2 x 5 x 5 x 5
Prime factors of 356 are 2 x 2 x 89
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 646, 455, 500, 356
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 455) = 293930
GCD(646, 455) = ( 646 x 455 ) / 293930
= 646 / 455
= 646
Step2:
LCM(1, 500) = 500
GCD(1, 500) = ( 1 x 500 ) / 500
= 1 / 500
= 1
Step3:
LCM(1, 356) = 356
GCD(1, 356) = ( 1 x 356 ) / 356
= 1 / 356
= 1
So, Greatest Common Divisor of 646, 455, 500, 356 is 1
