Given numbers are 663, 714, 646, 139
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(663, 714) = 9282
GCD(663, 714) = ( 663 x 714 ) / 9282
= 663 / 714
= 663
Step2:
LCM(51, 646) = 1938
GCD(51, 646) = ( 51 x 646 ) / 1938
= 51 / 646
= 51
Step3:
LCM(17, 139) = 2363
GCD(17, 139) = ( 17 x 139 ) / 2363
= 17 / 139
= 17
So, Greatest Common Divisor of 663, 714, 646, 139 is 1
