Steps to Calculate GCD of 217, 647, 792, 689 using LCM Formula

Given numbers are 217, 647, 792, 689

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

Apply this formula for all numbers.

Step1:

LCM(217, 647) = 140399

GCD(217, 647) = ( 217 x 647 ) / 140399

= 217 / 647

= 217


Step2:

LCM(1, 792) = 792

GCD(1, 792) = ( 1 x 792 ) / 792

= 1 / 792

= 1


Step3:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1


So, Greatest Common Divisor of 217, 647, 792, 689 is 1
