Given numbers are 772, 120, 619, 397
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(772, 120) = 23160
GCD(772, 120) = ( 772 x 120 ) / 23160
= 772 / 120
= 772
Step2:
LCM(4, 619) = 2476
GCD(4, 619) = ( 4 x 619 ) / 2476
= 4 / 619
= 4
Step3:
LCM(1, 397) = 397
GCD(1, 397) = ( 1 x 397 ) / 397
= 1 / 397
= 1
So, Greatest Common Divisor of 772, 120, 619, 397 is 1
