Given numbers are 248, 170, 387, 957

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

Apply this formula for all numbers.

Step1:

LCM(248, 170) = 21080

GCD(248, 170) = ( 248 x 170 ) / 21080

= 248 / 170

= 248

Step2:

LCM(2, 387) = 774

GCD(2, 387) = ( 2 x 387 ) / 774

= 2 / 387

= 2

Step3:

LCM(1, 957) = 957

GCD(1, 957) = ( 1 x 957 ) / 957

= 1 / 957

= 1

So, Greatest Common Divisor of 248, 170, 387, 957 is 1
