Given numbers are 253, 198, 127, 858

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

Apply this formula for all numbers.

Step1:

LCM(253, 198) = 4554

GCD(253, 198) = ( 253 x 198 ) / 4554

= 253 / 198

= 253

Step2:

LCM(11, 127) = 1397

GCD(11, 127) = ( 11 x 127 ) / 1397

= 11 / 127

= 11

Step3:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

So, Greatest Common Divisor of 253, 198, 127, 858 is 1
