GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 957) = 750288
GCD(784, 957) = ( 784 x 957 ) / 750288
= 784 / 957
= 784
Step2:
LCM(1, 768) = 768
GCD(1, 768) = ( 1 x 768 ) / 768
= 1 / 768
= 1
Step3:
LCM(1, 287) = 287
GCD(1, 287) = ( 1 x 287 ) / 287
= 1 / 287
= 1
So, Greatest Common Divisor of 784, 957, 768, 287 is 1
