Steps to Calculate GCD of 385, 213, 977, 402 using LCM Formula

Given numbers are 385, 213, 977, 402

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

Apply this formula for all numbers.

Step1:

LCM(385, 213) = 82005

GCD(385, 213) = ( 385 x 213 ) / 82005

= 385 / 213

= 385


Step2:

LCM(1, 977) = 977

GCD(1, 977) = ( 1 x 977 ) / 977

= 1 / 977

= 1


Step3:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1


So, Greatest Common Divisor of 385, 213, 977, 402 is 1
