1,2,4,5,8,10,17,20,34,40,68,85,136,170,340,680
Factors of 4253
List of positive integer factors of 4253 that divides 4253 without a remainder.
1,4253
Greatest Common Factor
We found the factors 680,4253 . The biggest common factor number is the GCF number.
So the greatest common factor 680,4253 is 1.
Lets's calculate LCM of 977,821
Given numbers has no common factors except 1. So, there LCM is their product i.e 802117
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/802117
Therefore, the GCF of Fractions 680/977,4253/821 is 1/802117
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 977,821 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(977,821) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(977,821) x common factors =1 x 1 = 1
LCM(977,821) = ( 977 × 821 ) / 1
LCM(977,821) = 802117 / 1
LCM(977,821) = 802117
