Steps to Calculate GCD of 660, 788, 231, 442 using LCM Formula

Given numbers are 660, 788, 231, 442

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

Apply this formula for all numbers.

Step1:

LCM(660, 788) = 130020

GCD(660, 788) = ( 660 x 788 ) / 130020

= 660 / 788

= 660


Step2:

LCM(4, 231) = 924

GCD(4, 231) = ( 4 x 231 ) / 924

= 4 / 231

= 4


Step3:

LCM(1, 442) = 442

GCD(1, 442) = ( 1 x 442 ) / 442

= 1 / 442

= 1


So, Greatest Common Divisor of 660, 788, 231, 442 is 1
