Given numbers are 871, 815, 615, 148

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

Apply this formula for all numbers.

Step1:

LCM(871, 815) = 709865

GCD(871, 815) = ( 871 x 815 ) / 709865

= 871 / 815

= 871

Step2:

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

= 1 / 615

= 1

Step3:

LCM(1, 148) = 148

GCD(1, 148) = ( 1 x 148 ) / 148

= 1 / 148

= 1

So, Greatest Common Divisor of 871, 815, 615, 148 is 1
