Given numbers are 561, 145, 868, 177
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 145) = 81345
GCD(561, 145) = ( 561 x 145 ) / 81345
= 561 / 145
= 561
Step2:
LCM(1, 868) = 868
GCD(1, 868) = ( 1 x 868 ) / 868
= 1 / 868
= 1
Step3:
LCM(1, 177) = 177
GCD(1, 177) = ( 1 x 177 ) / 177
= 1 / 177
= 1
So, Greatest Common Divisor of 561, 145, 868, 177 is 1
