Given numbers are 602, 649, 390, 277
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(602, 649) = 390698
GCD(602, 649) = ( 602 x 649 ) / 390698
= 602 / 649
= 602
Step2:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
Step3:
LCM(1, 277) = 277
GCD(1, 277) = ( 1 x 277 ) / 277
= 1 / 277
= 1
So, Greatest Common Divisor of 602, 649, 390, 277 is 1
