Given numbers are 281, 780, 108, 386
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(281, 780) = 219180
GCD(281, 780) = ( 281 x 780 ) / 219180
= 281 / 780
= 281
Step2:
LCM(1, 108) = 108
GCD(1, 108) = ( 1 x 108 ) / 108
= 1 / 108
= 1
Step3:
LCM(1, 386) = 386
GCD(1, 386) = ( 1 x 386 ) / 386
= 1 / 386
= 1
So, Greatest Common Divisor of 281, 780, 108, 386 is 1
