GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(688, 449) = 308912
GCD(688, 449) = ( 688 x 449 ) / 308912
= 688 / 449
= 688
Step2:
LCM(1, 549) = 549
GCD(1, 549) = ( 1 x 549 ) / 549
= 1 / 549
= 1
Step3:
LCM(1, 678) = 678
GCD(1, 678) = ( 1 x 678 ) / 678
= 1 / 678
= 1
So, Greatest Common Divisor of 688, 449, 549, 678 is 1
