Given numbers are 815, 402, 842, 179

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

Apply this formula for all numbers.

Step1:

LCM(815, 402) = 327630

GCD(815, 402) = ( 815 x 402 ) / 327630

= 815 / 402

= 815

Step2:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

Step3:

LCM(1, 179) = 179

GCD(1, 179) = ( 1 x 179 ) / 179

= 1 / 179

= 1

So, Greatest Common Divisor of 815, 402, 842, 179 is 1
