Prime factors of 828 are 2 x 2 x 3 x 3 x 23
Prime factors of 666 are 2 x 3 x 3 x 37
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 805, 780, 828, 666
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(805, 780) = 125580
GCD(805, 780) = ( 805 x 780 ) / 125580
= 805 / 780
= 805
Step2:
LCM(5, 828) = 4140
GCD(5, 828) = ( 5 x 828 ) / 4140
= 5 / 828
= 5
Step3:
LCM(1, 666) = 666
GCD(1, 666) = ( 1 x 666 ) / 666
= 1 / 666
= 1
So, Greatest Common Divisor of 805, 780, 828, 666 is 1
