Given numbers are 142, 111, 668, 971
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(142, 111) = 15762
GCD(142, 111) = ( 142 x 111 ) / 15762
= 142 / 111
= 142
Step2:
LCM(1, 668) = 668
GCD(1, 668) = ( 1 x 668 ) / 668
= 1 / 668
= 1
Step3:
LCM(1, 971) = 971
GCD(1, 971) = ( 1 x 971 ) / 971
= 1 / 971
= 1
So, Greatest Common Divisor of 142, 111, 668, 971 is 1
