Steps to Calculate GCD of 790, 315, 491, 247 using LCM Formula

Given numbers are 790, 315, 491, 247

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

Apply this formula for all numbers.

Step1:

LCM(790, 315) = 49770

GCD(790, 315) = ( 790 x 315 ) / 49770

= 790 / 315

= 790


Step2:

LCM(5, 491) = 2455

GCD(5, 491) = ( 5 x 491 ) / 2455

= 5 / 491

= 5


Step3:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1


So, Greatest Common Divisor of 790, 315, 491, 247 is 1
