GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(160, 646) = 51680
GCD(160, 646) = ( 160 x 646 ) / 51680
= 160 / 646
= 160
Step2:
LCM(2, 242) = 242
GCD(2, 242) = ( 2 x 242 ) / 242
= 2 / 242
= 2
Step3:
LCM(2, 476) = 476
GCD(2, 476) = ( 2 x 476 ) / 476
= 2 / 476
= 2
So, Greatest Common Divisor of 160, 646, 242, 476 is 2
