Given numbers are 784, 715, 314, 858
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 715) = 560560
GCD(784, 715) = ( 784 x 715 ) / 560560
= 784 / 715
= 784
Step2:
LCM(1, 314) = 314
GCD(1, 314) = ( 1 x 314 ) / 314
= 1 / 314
= 1
Step3:
LCM(1, 858) = 858
GCD(1, 858) = ( 1 x 858 ) / 858
= 1 / 858
= 1
So, Greatest Common Divisor of 784, 715, 314, 858 is 1
