Given numbers are 390, 568, 180, 145
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 568) = 110760
GCD(390, 568) = ( 390 x 568 ) / 110760
= 390 / 568
= 390
Step2:
LCM(2, 180) = 180
GCD(2, 180) = ( 2 x 180 ) / 180
= 2 / 180
= 2
Step3:
LCM(2, 145) = 290
GCD(2, 145) = ( 2 x 145 ) / 290
= 2 / 145
= 2
So, Greatest Common Divisor of 390, 568, 180, 145 is 1
