Given numbers are 256, 772, 611, 140
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(256, 772) = 49408
GCD(256, 772) = ( 256 x 772 ) / 49408
= 256 / 772
= 256
Step2:
LCM(4, 611) = 2444
GCD(4, 611) = ( 4 x 611 ) / 2444
= 4 / 611
= 4
Step3:
LCM(1, 140) = 140
GCD(1, 140) = ( 1 x 140 ) / 140
= 1 / 140
= 1
So, Greatest Common Divisor of 256, 772, 611, 140 is 1
