Given numbers are 399, 390, 634, 359
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(399, 390) = 51870
GCD(399, 390) = ( 399 x 390 ) / 51870
= 399 / 390
= 399
Step2:
LCM(3, 634) = 1902
GCD(3, 634) = ( 3 x 634 ) / 1902
= 3 / 634
= 3
Step3:
LCM(1, 359) = 359
GCD(1, 359) = ( 1 x 359 ) / 359
= 1 / 359
= 1
So, Greatest Common Divisor of 399, 390, 634, 359 is 1
