Given numbers are 406, 203, 495, 821
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(406, 203) = 406
GCD(406, 203) = ( 406 x 203 ) / 406
= 406 / 203
= 406
Step2:
LCM(203, 495) = 100485
GCD(203, 495) = ( 203 x 495 ) / 100485
= 203 / 495
= 203
Step3:
LCM(1, 821) = 821
GCD(1, 821) = ( 1 x 821 ) / 821
= 1 / 821
= 1
So, Greatest Common Divisor of 406, 203, 495, 821 is 1
