Steps to Calculate GCD of 556, 205, 817, 547 using LCM Formula

Given numbers are 556, 205, 817, 547

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

Apply this formula for all numbers.

Step1:

LCM(556, 205) = 113980

GCD(556, 205) = ( 556 x 205 ) / 113980

= 556 / 205

= 556


Step2:

LCM(1, 817) = 817

GCD(1, 817) = ( 1 x 817 ) / 817

= 1 / 817

= 1


Step3:

LCM(1, 547) = 547

GCD(1, 547) = ( 1 x 547 ) / 547

= 1 / 547

= 1


So, Greatest Common Divisor of 556, 205, 817, 547 is 1
