Given numbers are 436, 109, 405, 609
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(436, 109) = 436
GCD(436, 109) = ( 436 x 109 ) / 436
= 436 / 109
= 436
Step2:
LCM(109, 405) = 44145
GCD(109, 405) = ( 109 x 405 ) / 44145
= 109 / 405
= 109
Step3:
LCM(1, 609) = 609
GCD(1, 609) = ( 1 x 609 ) / 609
= 1 / 609
= 1
So, Greatest Common Divisor of 436, 109, 405, 609 is 1
