Given numbers are 465, 840, 795, 390
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(465, 840) = 26040
GCD(465, 840) = ( 465 x 840 ) / 26040
= 465 / 840
= 465
Step2:
LCM(15, 795) = 795
GCD(15, 795) = ( 15 x 795 ) / 795
= 15 / 795
= 15
Step3:
LCM(15, 390) = 390
GCD(15, 390) = ( 15 x 390 ) / 390
= 15 / 390
= 15
So, Greatest Common Divisor of 465, 840, 795, 390 is 15
