Given numbers are 390, 675, 179, 997
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 675) = 17550
GCD(390, 675) = ( 390 x 675 ) / 17550
= 390 / 675
= 390
Step2:
LCM(15, 179) = 2685
GCD(15, 179) = ( 15 x 179 ) / 2685
= 15 / 179
= 15
Step3:
LCM(1, 997) = 997
GCD(1, 997) = ( 1 x 997 ) / 997
= 1 / 997
= 1
So, Greatest Common Divisor of 390, 675, 179, 997 is 1
