Steps to Calculate GCD of 620, 803, 747, 961 using LCM Formula

Given numbers are 620, 803, 747, 961

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

Apply this formula for all numbers.

Step1:

LCM(620, 803) = 497860

GCD(620, 803) = ( 620 x 803 ) / 497860

= 620 / 803

= 620


Step2:

LCM(1, 747) = 747

GCD(1, 747) = ( 1 x 747 ) / 747

= 1 / 747

= 1


Step3:

LCM(1, 961) = 961

GCD(1, 961) = ( 1 x 961 ) / 961

= 1 / 961

= 1


So, Greatest Common Divisor of 620, 803, 747, 961 is 1
