Steps to Calculate GCD of 823, 180, 225, 660 using LCM Formula

Given numbers are 823, 180, 225, 660

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

Apply this formula for all numbers.

Step1:

LCM(823, 180) = 148140

GCD(823, 180) = ( 823 x 180 ) / 148140

= 823 / 180

= 823


Step2:

LCM(1, 225) = 225

GCD(1, 225) = ( 1 x 225 ) / 225

= 1 / 225

= 1


Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1


So, Greatest Common Divisor of 823, 180, 225, 660 is 1
