Given numbers are 311, 170, 776, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(311, 170) = 52870
GCD(311, 170) = ( 311 x 170 ) / 52870
= 311 / 170
= 311
Step2:
LCM(1, 776) = 776
GCD(1, 776) = ( 1 x 776 ) / 776
= 1 / 776
= 1
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 311, 170, 776, 644 is 1
