Given numbers are 680, 649, 928, 515
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 649) = 441320
GCD(680, 649) = ( 680 x 649 ) / 441320
= 680 / 649
= 680
Step2:
LCM(1, 928) = 928
GCD(1, 928) = ( 1 x 928 ) / 928
= 1 / 928
= 1
Step3:
LCM(1, 515) = 515
GCD(1, 515) = ( 1 x 515 ) / 515
= 1 / 515
= 1
So, Greatest Common Divisor of 680, 649, 928, 515 is 1
