Given numbers are 248, 840, 658

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

Apply this formula for all numbers.

Step1:

LCM(248, 840) = 26040

GCD(248, 840) = ( 248 x 840 ) / 26040

= 248 / 840

= 248

Step2:

LCM(8, 658) = 2632

GCD(8, 658) = ( 8 x 658 ) / 2632

= 8 / 658

= 8

So, Greatest Common Divisor of 248, 840, 658 is 2
