Given numbers are 987, 931, 623, 834
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 931) = 131271
GCD(987, 931) = ( 987 x 931 ) / 131271
= 987 / 931
= 987
Step2:
LCM(7, 623) = 623
GCD(7, 623) = ( 7 x 623 ) / 623
= 7 / 623
= 7
Step3:
LCM(7, 834) = 5838
GCD(7, 834) = ( 7 x 834 ) / 5838
= 7 / 834
= 7
So, Greatest Common Divisor of 987, 931, 623, 834 is 1
