Given numbers are 508, 215, 421, 390
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(508, 215) = 109220
GCD(508, 215) = ( 508 x 215 ) / 109220
= 508 / 215
= 508
Step2:
LCM(1, 421) = 421
GCD(1, 421) = ( 1 x 421 ) / 421
= 1 / 421
= 1
Step3:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
So, Greatest Common Divisor of 508, 215, 421, 390 is 1
