GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 704) = 34496
GCD(784, 704) = ( 784 x 704 ) / 34496
= 784 / 704
= 784
Step2:
LCM(16, 450) = 3600
GCD(16, 450) = ( 16 x 450 ) / 3600
= 16 / 450
= 16
Step3:
LCM(2, 156) = 156
GCD(2, 156) = ( 2 x 156 ) / 156
= 2 / 156
= 2
So, Greatest Common Divisor of 784, 704, 450, 156 is 2
