Given numbers are 289, 656, 407, 147
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(289, 656) = 189584
GCD(289, 656) = ( 289 x 656 ) / 189584
= 289 / 656
= 289
Step2:
LCM(1, 407) = 407
GCD(1, 407) = ( 1 x 407 ) / 407
= 1 / 407
= 1
Step3:
LCM(1, 147) = 147
GCD(1, 147) = ( 1 x 147 ) / 147
= 1 / 147
= 1
So, Greatest Common Divisor of 289, 656, 407, 147 is 1
