Steps to Calculate GCD of 520, 145, 712, 666 using LCM Formula

Given numbers are 520, 145, 712, 666

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

Apply this formula for all numbers.

Step1:

LCM(520, 145) = 15080

GCD(520, 145) = ( 520 x 145 ) / 15080

= 520 / 145

= 520


Step2:

LCM(5, 712) = 3560

GCD(5, 712) = ( 5 x 712 ) / 3560

= 5 / 712

= 5


Step3:

LCM(1, 666) = 666

GCD(1, 666) = ( 1 x 666 ) / 666

= 1 / 666

= 1


So, Greatest Common Divisor of 520, 145, 712, 666 is 1
