The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 816, 900, 821, 641
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(816, 900) = 61200
GCD(816, 900) = ( 816 x 900 ) / 61200
= 816 / 900
= 816
Step2:
LCM(12, 821) = 9852
GCD(12, 821) = ( 12 x 821 ) / 9852
= 12 / 821
= 12
Step3:
LCM(1, 641) = 641
GCD(1, 641) = ( 1 x 641 ) / 641
= 1 / 641
= 1
So, Greatest Common Divisor of 816, 900, 821, 641 is 1
