Given numbers are 649, 332, 639, 371
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 332) = 215468
GCD(649, 332) = ( 649 x 332 ) / 215468
= 649 / 332
= 649
Step2:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
Step3:
LCM(1, 371) = 371
GCD(1, 371) = ( 1 x 371 ) / 371
= 1 / 371
= 1
So, Greatest Common Divisor of 649, 332, 639, 371 is 1
