Steps to Calculate GCD of 442, 581, 309, 782 using LCM Formula
Given numbers are 442, 581, 309, 782
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(442, 581) = 256802
GCD(442, 581) = ( 442 x 581 ) / 256802
= 442 / 581
= 442
Step2:
LCM(1, 309) = 309
GCD(1, 309) = ( 1 x 309 ) / 309
= 1 / 309
= 1
Step3:
LCM(1, 782) = 782
GCD(1, 782) = ( 1 x 782 ) / 782
= 1 / 782
= 1
So, Greatest Common Divisor of 442, 581, 309, 782 is 1
