GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(429, 153) = 21879
GCD(429, 153) = ( 429 x 153 ) / 21879
= 429 / 153
= 429
Step2:
LCM(3, 671) = 2013
GCD(3, 671) = ( 3 x 671 ) / 2013
= 3 / 671
= 3
Step3:
LCM(1, 688) = 688
GCD(1, 688) = ( 1 x 688 ) / 688
= 1 / 688
= 1
So, Greatest Common Divisor of 429, 153, 671, 688 is 1
