GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(177, 686) = 121422
GCD(177, 686) = ( 177 x 686 ) / 121422
= 177 / 686
= 177
Step2:
LCM(1, 504) = 504
GCD(1, 504) = ( 1 x 504 ) / 504
= 1 / 504
= 1
Step3:
LCM(1, 784) = 784
GCD(1, 784) = ( 1 x 784 ) / 784
= 1 / 784
= 1
So, Greatest Common Divisor of 177, 686, 504, 784 is 1
