Given numbers are 620, 385, 865, 536
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 385) = 47740
GCD(620, 385) = ( 620 x 385 ) / 47740
= 620 / 385
= 620
Step2:
LCM(5, 865) = 865
GCD(5, 865) = ( 5 x 865 ) / 865
= 5 / 865
= 5
Step3:
LCM(5, 536) = 2680
GCD(5, 536) = ( 5 x 536 ) / 2680
= 5 / 536
= 5
So, Greatest Common Divisor of 620, 385, 865, 536 is 1
