Given numbers are 784, 800, 294, 640
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 800) = 39200
GCD(784, 800) = ( 784 x 800 ) / 39200
= 784 / 800
= 784
Step2:
LCM(16, 294) = 2352
GCD(16, 294) = ( 16 x 294 ) / 2352
= 16 / 294
= 16
Step3:
LCM(2, 640) = 640
GCD(2, 640) = ( 2 x 640 ) / 640
= 2 / 640
= 2
So, Greatest Common Divisor of 784, 800, 294, 640 is 2
