Steps to Calculate GCD of 782, 915, 430, 424 using LCM Formula

Given numbers are 782, 915, 430, 424

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

Apply this formula for all numbers.

Step1:

LCM(782, 915) = 715530

GCD(782, 915) = ( 782 x 915 ) / 715530

= 782 / 915

= 782


Step2:

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

= 1 / 430

= 1


Step3:

LCM(1, 424) = 424

GCD(1, 424) = ( 1 x 424 ) / 424

= 1 / 424

= 1


So, Greatest Common Divisor of 782, 915, 430, 424 is 1
