Given numbers are 465, 855, 289, 609
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(465, 855) = 26505
GCD(465, 855) = ( 465 x 855 ) / 26505
= 465 / 855
= 465
Step2:
LCM(15, 289) = 4335
GCD(15, 289) = ( 15 x 289 ) / 4335
= 15 / 289
= 15
Step3:
LCM(1, 609) = 609
GCD(1, 609) = ( 1 x 609 ) / 609
= 1 / 609
= 1
So, Greatest Common Divisor of 465, 855, 289, 609 is 1
