GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(458, 994) = 227626
GCD(458, 994) = ( 458 x 994 ) / 227626
= 458 / 994
= 458
Step2:
LCM(2, 784) = 784
GCD(2, 784) = ( 2 x 784 ) / 784
= 2 / 784
= 2
Step3:
LCM(2, 157) = 314
GCD(2, 157) = ( 2 x 157 ) / 314
= 2 / 157
= 2
So, Greatest Common Divisor of 458, 994, 784, 157 is 1
