Given numbers are 148, 262, 870, 815

The list of prime factors of all numbers are

Prime factors of 148 are 2 x 2 x 37

Prime factors of 262 are 2 x 131

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

Prime factors of 815 are 5 x 163

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

Given numbers are 148, 262, 870, 815

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

Apply this formula for all numbers.

Step1:

LCM(148, 262) = 19388

GCD(148, 262) = ( 148 x 262 ) / 19388

= 148 / 262

= 148

Step2:

LCM(2, 870) = 870

GCD(2, 870) = ( 2 x 870 ) / 870

= 2 / 870

= 2

Step3:

LCM(2, 815) = 1630

GCD(2, 815) = ( 2 x 815 ) / 1630

= 2 / 815

= 2

So, Greatest Common Divisor of 148, 262, 870, 815 is 1
