Given numbers are 858, 657, 961, 149

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

Apply this formula for all numbers.

Step1:

LCM(858, 657) = 187902

GCD(858, 657) = ( 858 x 657 ) / 187902

= 858 / 657

= 858

Step2:

LCM(3, 961) = 2883

GCD(3, 961) = ( 3 x 961 ) / 2883

= 3 / 961

= 3

Step3:

LCM(1, 149) = 149

GCD(1, 149) = ( 1 x 149 ) / 149

= 1 / 149

= 1

So, Greatest Common Divisor of 858, 657, 961, 149 is 1
