GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(857, 392) = 335944
GCD(857, 392) = ( 857 x 392 ) / 335944
= 857 / 392
= 857
Step2:
LCM(1, 515) = 515
GCD(1, 515) = ( 1 x 515 ) / 515
= 1 / 515
= 1
Step3:
LCM(1, 279) = 279
GCD(1, 279) = ( 1 x 279 ) / 279
= 1 / 279
= 1
So, Greatest Common Divisor of 857, 392, 515, 279 is 1
