Given numbers are 861, 470, 72, 277
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 470) = 404670
GCD(861, 470) = ( 861 x 470 ) / 404670
= 861 / 470
= 861
Step2:
LCM(1, 72) = 72
GCD(1, 72) = ( 1 x 72 ) / 72
= 1 / 72
= 1
Step3:
LCM(1, 277) = 277
GCD(1, 277) = ( 1 x 277 ) / 277
= 1 / 277
= 1
So, Greatest Common Divisor of 861, 470, 72, 277 is 1
