GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(654, 387) = 84366
GCD(654, 387) = ( 654 x 387 ) / 84366
= 654 / 387
= 654
Step2:
LCM(3, 239) = 717
GCD(3, 239) = ( 3 x 239 ) / 717
= 3 / 239
= 3
Step3:
LCM(1, 915) = 915
GCD(1, 915) = ( 1 x 915 ) / 915
= 1 / 915
= 1
So, Greatest Common Divisor of 654, 387, 239, 915 is 1
