Given numbers are 157, 743, 644, 111
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(157, 743) = 116651
GCD(157, 743) = ( 157 x 743 ) / 116651
= 157 / 743
= 157
Step2:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
Step3:
LCM(1, 111) = 111
GCD(1, 111) = ( 1 x 111 ) / 111
= 1 / 111
= 1
So, Greatest Common Divisor of 157, 743, 644, 111 is 1
