Given numbers are 870, 851, 270, 661

The list of prime factors of all numbers are

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 851 are 23 x 37

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

Prime factors of 661 are 661

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 870, 851, 270, 661

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

Apply this formula for all numbers.

Step1:

LCM(870, 851) = 740370

GCD(870, 851) = ( 870 x 851 ) / 740370

= 870 / 851

= 870

Step2:

LCM(1, 270) = 270

GCD(1, 270) = ( 1 x 270 ) / 270

= 1 / 270

= 1

Step3:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

So, Greatest Common Divisor of 870, 851, 270, 661 is 1
