Given numbers are 390, 568, 450, 895
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, 450) = 450
GCD(2, 450) = ( 2 x 450 ) / 450
= 2 / 450
= 2
Step3:
LCM(2, 895) = 1790
GCD(2, 895) = ( 2 x 895 ) / 1790
= 2 / 895
= 2
So, Greatest Common Divisor of 390, 568, 450, 895 is 1
