Given numbers are 395, 445, 643, 486
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(395, 445) = 35155
GCD(395, 445) = ( 395 x 445 ) / 35155
= 395 / 445
= 395
Step2:
LCM(5, 643) = 3215
GCD(5, 643) = ( 5 x 643 ) / 3215
= 5 / 643
= 5
Step3:
LCM(1, 486) = 486
GCD(1, 486) = ( 1 x 486 ) / 486
= 1 / 486
= 1
So, Greatest Common Divisor of 395, 445, 643, 486 is 1
