Given numbers are 647, 142, 110, 123
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(647, 142) = 91874
GCD(647, 142) = ( 647 x 142 ) / 91874
= 647 / 142
= 647
Step2:
LCM(1, 110) = 110
GCD(1, 110) = ( 1 x 110 ) / 110
= 1 / 110
= 1
Step3:
LCM(1, 123) = 123
GCD(1, 123) = ( 1 x 123 ) / 123
= 1 / 123
= 1
So, Greatest Common Divisor of 647, 142, 110, 123 is 1
