Steps to Calculate GCD of 665, 993, 257, 386 using LCM Formula

Given numbers are 665, 993, 257, 386

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

Apply this formula for all numbers.

Step1:

LCM(665, 993) = 660345

GCD(665, 993) = ( 665 x 993 ) / 660345

= 665 / 993

= 665


Step2:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1


Step3:

LCM(1, 386) = 386

GCD(1, 386) = ( 1 x 386 ) / 386

= 1 / 386

= 1


So, Greatest Common Divisor of 665, 993, 257, 386 is 1
