Steps to Calculate GCD of 645, 694, 224, 830 using LCM Formula

Given numbers are 645, 694, 224, 830

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

Apply this formula for all numbers.

Step1:

LCM(645, 694) = 447630

GCD(645, 694) = ( 645 x 694 ) / 447630

= 645 / 694

= 645


Step2:

LCM(1, 224) = 224

GCD(1, 224) = ( 1 x 224 ) / 224

= 1 / 224

= 1


Step3:

LCM(1, 830) = 830

GCD(1, 830) = ( 1 x 830 ) / 830

= 1 / 830

= 1


So, Greatest Common Divisor of 645, 694, 224, 830 is 1
