Given numbers are 657, 261, 562, 128
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(657, 261) = 19053
GCD(657, 261) = ( 657 x 261 ) / 19053
= 657 / 261
= 657
Step2:
LCM(9, 562) = 5058
GCD(9, 562) = ( 9 x 562 ) / 5058
= 9 / 562
= 9
Step3:
LCM(1, 128) = 128
GCD(1, 128) = ( 1 x 128 ) / 128
= 1 / 128
= 1
So, Greatest Common Divisor of 657, 261, 562, 128 is 1
