Steps to Calculate GCD of 208, 435, 168, 561 using LCM Formula

Given numbers are 208, 435, 168, 561

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

Apply this formula for all numbers.

Step1:

LCM(208, 435) = 90480

GCD(208, 435) = ( 208 x 435 ) / 90480

= 208 / 435

= 208


Step2:

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

= 1 / 168

= 1


Step3:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1


So, Greatest Common Divisor of 208, 435, 168, 561 is 1
