Given numbers are 647, 238, 170, 911
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(647, 238) = 153986
GCD(647, 238) = ( 647 x 238 ) / 153986
= 647 / 238
= 647
Step2:
LCM(1, 170) = 170
GCD(1, 170) = ( 1 x 170 ) / 170
= 1 / 170
= 1
Step3:
LCM(1, 911) = 911
GCD(1, 911) = ( 1 x 911 ) / 911
= 1 / 911
= 1
So, Greatest Common Divisor of 647, 238, 170, 911 is 1
