Steps to Calculate GCD of 308, 909, 155, 478 using LCM Formula

Given numbers are 308, 909, 155, 478

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

Apply this formula for all numbers.

Step1:

LCM(308, 909) = 279972

GCD(308, 909) = ( 308 x 909 ) / 279972

= 308 / 909

= 308


Step2:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1


Step3:

LCM(1, 478) = 478

GCD(1, 478) = ( 1 x 478 ) / 478

= 1 / 478

= 1


So, Greatest Common Divisor of 308, 909, 155, 478 is 1
