Given numbers are 861, 137, 888, 631
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 137) = 117957
GCD(861, 137) = ( 861 x 137 ) / 117957
= 861 / 137
= 861
Step2:
LCM(1, 888) = 888
GCD(1, 888) = ( 1 x 888 ) / 888
= 1 / 888
= 1
Step3:
LCM(1, 631) = 631
GCD(1, 631) = ( 1 x 631 ) / 631
= 1 / 631
= 1
So, Greatest Common Divisor of 861, 137, 888, 631 is 1
