Steps to Calculate GCD of 943, 861, 27, 987 using LCM Formula
Given numbers are 943, 861, 27, 987
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(943, 861) = 19803
GCD(943, 861) = ( 943 x 861 ) / 19803
= 943 / 861
= 943
Step2:
LCM(41, 27) = 1107
GCD(41, 27) = ( 41 x 27 ) / 1107
= 41 / 27
= 41
Step3:
LCM(1, 987) = 987
GCD(1, 987) = ( 1 x 987 ) / 987
= 1 / 987
= 1
So, Greatest Common Divisor of 943, 861, 27, 987 is 1
