Given numbers are 561, 858, 186, 354

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

Apply this formula for all numbers.

Step1:

LCM(561, 858) = 14586

GCD(561, 858) = ( 561 x 858 ) / 14586

= 561 / 858

= 561

Step2:

LCM(33, 186) = 2046

GCD(33, 186) = ( 33 x 186 ) / 2046

= 33 / 186

= 33

Step3:

LCM(3, 354) = 354

GCD(3, 354) = ( 3 x 354 ) / 354

= 3 / 354

= 3

So, Greatest Common Divisor of 561, 858, 186, 354 is 3
