Given numbers are 647, 581, 222, 135
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(647, 581) = 375907
GCD(647, 581) = ( 647 x 581 ) / 375907
= 647 / 581
= 647
Step2:
LCM(1, 222) = 222
GCD(1, 222) = ( 1 x 222 ) / 222
= 1 / 222
= 1
Step3:
LCM(1, 135) = 135
GCD(1, 135) = ( 1 x 135 ) / 135
= 1 / 135
= 1
So, Greatest Common Divisor of 647, 581, 222, 135 is 1
