Given numbers are 556, 372, 991, 857

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(556, 372) = 51708

GCD(556, 372) = ( 556 x 372 ) / 51708

= 556 / 372

= 556

Step2:

LCM(4, 991) = 3964

GCD(4, 991) = ( 4 x 991 ) / 3964

= 4 / 991

= 4

Step3:

LCM(1, 857) = 857

GCD(1, 857) = ( 1 x 857 ) / 857

= 1 / 857

= 1

So, Greatest Common Divisor of 556, 372, 991, 857 is 1
