Given numbers are 949, 731, 612, 138
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(949, 731) = 693719
GCD(949, 731) = ( 949 x 731 ) / 693719
= 949 / 731
= 949
Step2:
LCM(1, 612) = 612
GCD(1, 612) = ( 1 x 612 ) / 612
= 1 / 612
= 1
Step3:
LCM(1, 138) = 138
GCD(1, 138) = ( 1 x 138 ) / 138
= 1 / 138
= 1
So, Greatest Common Divisor of 949, 731, 612, 138 is 1
