Given numbers are 109, 255, 177, 661
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(109, 255) = 27795
GCD(109, 255) = ( 109 x 255 ) / 27795
= 109 / 255
= 109
Step2:
LCM(1, 177) = 177
GCD(1, 177) = ( 1 x 177 ) / 177
= 1 / 177
= 1
Step3:
LCM(1, 661) = 661
GCD(1, 661) = ( 1 x 661 ) / 661
= 1 / 661
= 1
So, Greatest Common Divisor of 109, 255, 177, 661 is 1
