Given numbers are 820, 666, 887, 391
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(820, 666) = 273060
GCD(820, 666) = ( 820 x 666 ) / 273060
= 820 / 666
= 820
Step2:
LCM(2, 887) = 1774
GCD(2, 887) = ( 2 x 887 ) / 1774
= 2 / 887
= 2
Step3:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
So, Greatest Common Divisor of 820, 666, 887, 391 is 1
