Steps to Calculate GCD of 257, 309, 233, 442 using LCM Formula
Given numbers are 257, 309, 233, 442
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(257, 309) = 79413
GCD(257, 309) = ( 257 x 309 ) / 79413
= 257 / 309
= 257
Step2:
LCM(1, 233) = 233
GCD(1, 233) = ( 1 x 233 ) / 233
= 1 / 233
= 1
Step3:
LCM(1, 442) = 442
GCD(1, 442) = ( 1 x 442 ) / 442
= 1 / 442
= 1
So, Greatest Common Divisor of 257, 309, 233, 442 is 1
