GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 575) = 44850
GCD(390, 575) = ( 390 x 575 ) / 44850
= 390 / 575
= 390
Step2:
LCM(5, 768) = 3840
GCD(5, 768) = ( 5 x 768 ) / 3840
= 5 / 768
= 5
Step3:
LCM(1, 953) = 953
GCD(1, 953) = ( 1 x 953 ) / 953
= 1 / 953
= 1
So, Greatest Common Divisor of 390, 575, 768, 953 is 1
