Steps to Calculate GCD of 658, 647, 570, 449 using LCM Formula

Given numbers are 658, 647, 570, 449

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

Apply this formula for all numbers.

Step1:

LCM(658, 647) = 425726

GCD(658, 647) = ( 658 x 647 ) / 425726

= 658 / 647

= 658


Step2:

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

= 1 / 570

= 1


Step3:

LCM(1, 449) = 449

GCD(1, 449) = ( 1 x 449 ) / 449

= 1 / 449

= 1


So, Greatest Common Divisor of 658, 647, 570, 449 is 1
