Given numbers are 861, 177, 439, 608
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 177) = 50799
GCD(861, 177) = ( 861 x 177 ) / 50799
= 861 / 177
= 861
Step2:
LCM(3, 439) = 1317
GCD(3, 439) = ( 3 x 439 ) / 1317
= 3 / 439
= 3
Step3:
LCM(1, 608) = 608
GCD(1, 608) = ( 1 x 608 ) / 608
= 1 / 608
= 1
So, Greatest Common Divisor of 861, 177, 439, 608 is 1
