Finding GCD of 278, 802, 991 using LCM Formula

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(278, 802) = 111478

GCD(278, 802) = ( 278 x 802 ) / 111478

GCD(278, 802) = 222956 / 111478

GCD(278, 802) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 991

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(2, 991) = 1982

GCD(2, 991) = ( 2 x 991 ) / 1982

GCD(2, 991) = 1982 / 1982

GCD(2, 991) = 1

GCD of 278, 802, 991 is 1
