Steps to Calculate GCD of 405, 986, 102, 670 using LCM Formula

Given numbers are 405, 986, 102, 670

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

Apply this formula for all numbers.

Step1:

LCM(405, 986) = 399330

GCD(405, 986) = ( 405 x 986 ) / 399330

= 405 / 986

= 405


Step2:

LCM(1, 102) = 102

GCD(1, 102) = ( 1 x 102 ) / 102

= 1 / 102

= 1


Step3:

LCM(1, 670) = 670

GCD(1, 670) = ( 1 x 670 ) / 670

= 1 / 670

= 1


So, Greatest Common Divisor of 405, 986, 102, 670 is 1
