Given numbers are 123, 138, 677, 652
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(123, 138) = 5658
GCD(123, 138) = ( 123 x 138 ) / 5658
= 123 / 138
= 123
Step2:
LCM(3, 677) = 2031
GCD(3, 677) = ( 3 x 677 ) / 2031
= 3 / 677
= 3
Step3:
LCM(1, 652) = 652
GCD(1, 652) = ( 1 x 652 ) / 652
= 1 / 652
= 1
So, Greatest Common Divisor of 123, 138, 677, 652 is 1
