Steps to Calculate GCD of 660, 630, 619, 217 using LCM Formula

Given numbers are 660, 630, 619, 217

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

Apply this formula for all numbers.

Step1:

LCM(660, 630) = 13860

GCD(660, 630) = ( 660 x 630 ) / 13860

= 660 / 630

= 660


Step2:

LCM(30, 619) = 18570

GCD(30, 619) = ( 30 x 619 ) / 18570

= 30 / 619

= 30


Step3:

LCM(1, 217) = 217

GCD(1, 217) = ( 1 x 217 ) / 217

= 1 / 217

= 1


So, Greatest Common Divisor of 660, 630, 619, 217 is 1
