Steps to Calculate GCD of 820, 478, 287, 788 using LCM Formula
Given numbers are 820, 478, 287, 788
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(820, 478) = 195980
GCD(820, 478) = ( 820 x 478 ) / 195980
= 820 / 478
= 820
Step2:
LCM(2, 287) = 574
GCD(2, 287) = ( 2 x 287 ) / 574
= 2 / 287
= 2
Step3:
LCM(1, 788) = 788
GCD(1, 788) = ( 1 x 788 ) / 788
= 1 / 788
= 1
So, Greatest Common Divisor of 820, 478, 287, 788 is 1
