Steps to Calculate GCD of 490, 766, 19, 581 using LCM Formula
Given numbers are 490, 766, 19, 581
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(490, 766) = 187670
GCD(490, 766) = ( 490 x 766 ) / 187670
= 490 / 766
= 490
Step2:
LCM(2, 19) = 38
GCD(2, 19) = ( 2 x 19 ) / 38
= 2 / 19
= 2
Step3:
LCM(1, 581) = 581
GCD(1, 581) = ( 1 x 581 ) / 581
= 1 / 581
= 1
So, Greatest Common Divisor of 490, 766, 19, 581 is 1
