GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(116, 520) = 15080
GCD(116, 520) = ( 116 x 520 ) / 15080
= 116 / 520
= 116
Step2:
LCM(4, 404) = 404
GCD(4, 404) = ( 4 x 404 ) / 404
= 4 / 404
= 4
Step3:
LCM(4, 646) = 1292
GCD(4, 646) = ( 4 x 646 ) / 1292
= 4 / 646
= 4
So, Greatest Common Divisor of 116, 520, 404, 646 is 2
