Given numbers are 207, 891, 142, 957

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

Apply this formula for all numbers.

Step1:

LCM(207, 891) = 20493

GCD(207, 891) = ( 207 x 891 ) / 20493

= 207 / 891

= 207

Step2:

LCM(9, 142) = 1278

GCD(9, 142) = ( 9 x 142 ) / 1278

= 9 / 142

= 9

Step3:

LCM(1, 957) = 957

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

= 1 / 957

= 1

So, Greatest Common Divisor of 207, 891, 142, 957 is 1
