GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 546) = 185640
GCD(680, 546) = ( 680 x 546 ) / 185640
= 680 / 546
= 680
Step2:
LCM(2, 452) = 452
GCD(2, 452) = ( 2 x 452 ) / 452
= 2 / 452
= 2
Step3:
LCM(2, 666) = 666
GCD(2, 666) = ( 2 x 666 ) / 666
= 2 / 666
= 2
So, Greatest Common Divisor of 680, 546, 452, 666 is 2
