Given numbers are 520, 171, 57, 916
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(520, 171) = 88920
GCD(520, 171) = ( 520 x 171 ) / 88920
= 520 / 171
= 520
Step2:
LCM(1, 57) = 57
GCD(1, 57) = ( 1 x 57 ) / 57
= 1 / 57
= 1
Step3:
LCM(1, 916) = 916
GCD(1, 916) = ( 1 x 916 ) / 916
= 1 / 916
= 1
So, Greatest Common Divisor of 520, 171, 57, 916 is 1
