Given numbers are 278, 878, 390, 801
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 878) = 122042
GCD(278, 878) = ( 278 x 878 ) / 122042
= 278 / 878
= 278
Step2:
LCM(2, 390) = 390
GCD(2, 390) = ( 2 x 390 ) / 390
= 2 / 390
= 2
Step3:
LCM(2, 801) = 1602
GCD(2, 801) = ( 2 x 801 ) / 1602
= 2 / 801
= 2
So, Greatest Common Divisor of 278, 878, 390, 801 is 1
