Given numbers are 311, 642, 671, 885
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(311, 642) = 199662
GCD(311, 642) = ( 311 x 642 ) / 199662
= 311 / 642
= 311
Step2:
LCM(1, 671) = 671
GCD(1, 671) = ( 1 x 671 ) / 671
= 1 / 671
= 1
Step3:
LCM(1, 885) = 885
GCD(1, 885) = ( 1 x 885 ) / 885
= 1 / 885
= 1
So, Greatest Common Divisor of 311, 642, 671, 885 is 1
