Given numbers are 861, 427, 983, 125
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 427) = 52521
GCD(861, 427) = ( 861 x 427 ) / 52521
= 861 / 427
= 861
Step2:
LCM(7, 983) = 6881
GCD(7, 983) = ( 7 x 983 ) / 6881
= 7 / 983
= 7
Step3:
LCM(1, 125) = 125
GCD(1, 125) = ( 1 x 125 ) / 125
= 1 / 125
= 1
So, Greatest Common Divisor of 861, 427, 983, 125 is 1
