GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(868, 784) = 24304
GCD(868, 784) = ( 868 x 784 ) / 24304
= 868 / 784
= 868
Step2:
LCM(28, 657) = 18396
GCD(28, 657) = ( 28 x 657 ) / 18396
= 28 / 657
= 28
Step3:
LCM(1, 579) = 579
GCD(1, 579) = ( 1 x 579 ) / 579
= 1 / 579
= 1
So, Greatest Common Divisor of 868, 784, 657, 579 is 1
