Given numbers are 423, 108, 365, 520
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(423, 108) = 5076
GCD(423, 108) = ( 423 x 108 ) / 5076
= 423 / 108
= 423
Step2:
LCM(9, 365) = 3285
GCD(9, 365) = ( 9 x 365 ) / 3285
= 9 / 365
= 9
Step3:
LCM(1, 520) = 520
GCD(1, 520) = ( 1 x 520 ) / 520
= 1 / 520
= 1
So, Greatest Common Divisor of 423, 108, 365, 520 is 1
