Given numbers are 676, 432, 861, 687
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(676, 432) = 73008
GCD(676, 432) = ( 676 x 432 ) / 73008
= 676 / 432
= 676
Step2:
LCM(4, 861) = 3444
GCD(4, 861) = ( 4 x 861 ) / 3444
= 4 / 861
= 4
Step3:
LCM(1, 687) = 687
GCD(1, 687) = ( 1 x 687 ) / 687
= 1 / 687
= 1
So, Greatest Common Divisor of 676, 432, 861, 687 is 1
