Steps to Calculate GCD of 170, 398, 755, 217 using LCM Formula

Given numbers are 170, 398, 755, 217

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

Apply this formula for all numbers.

Step1:

LCM(170, 398) = 33830

GCD(170, 398) = ( 170 x 398 ) / 33830

= 170 / 398

= 170


Step2:

LCM(2, 755) = 1510

GCD(2, 755) = ( 2 x 755 ) / 1510

= 2 / 755

= 2


Step3:

LCM(1, 217) = 217

GCD(1, 217) = ( 1 x 217 ) / 217

= 1 / 217

= 1


So, Greatest Common Divisor of 170, 398, 755, 217 is 1
