Given numbers are 248, 558, 70, 791

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

Apply this formula for all numbers.

Step1:

LCM(248, 558) = 2232

GCD(248, 558) = ( 248 x 558 ) / 2232

= 248 / 558

= 248

Step2:

LCM(62, 70) = 2170

GCD(62, 70) = ( 62 x 70 ) / 2170

= 62 / 70

= 62

Step3:

LCM(2, 791) = 1582

GCD(2, 791) = ( 2 x 791 ) / 1582

= 2 / 791

= 2

So, Greatest Common Divisor of 248, 558, 70, 791 is 1
