Given numbers are 399, 381, 340, 662
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(399, 381) = 50673
GCD(399, 381) = ( 399 x 381 ) / 50673
= 399 / 381
= 399
Step2:
LCM(3, 340) = 1020
GCD(3, 340) = ( 3 x 340 ) / 1020
= 3 / 340
= 3
Step3:
LCM(1, 662) = 662
GCD(1, 662) = ( 1 x 662 ) / 662
= 1 / 662
= 1
So, Greatest Common Divisor of 399, 381, 340, 662 is 1
