Given numbers are 987, 643, 681, 882
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 643) = 634641
GCD(987, 643) = ( 987 x 643 ) / 634641
= 987 / 643
= 987
Step2:
LCM(1, 681) = 681
GCD(1, 681) = ( 1 x 681 ) / 681
= 1 / 681
= 1
Step3:
LCM(1, 882) = 882
GCD(1, 882) = ( 1 x 882 ) / 882
= 1 / 882
= 1
So, Greatest Common Divisor of 987, 643, 681, 882 is 1
