HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1243, 6170 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1243, 6170 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 1243, 6170 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 1243, 6170 is 1.
HCF(1243, 6170) = 1
HCF of 1243, 6170 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1243, 6170 is 1.
Highest Common Factor of 1243,6170 is 1
Step 1: Since 6170 > 1243, we apply the division lemma to 6170 and 1243, to get
6170 = 1243 x 4 + 1198
Step 2: Since the reminder 1243 ≠ 0, we apply division lemma to 1198 and 1243, to get
1243 = 1198 x 1 + 45
Step 3: We consider the new divisor 1198 and the new remainder 45, and apply the division lemma to get
1198 = 45 x 26 + 28
We consider the new divisor 45 and the new remainder 28,and apply the division lemma to get
45 = 28 x 1 + 17
We consider the new divisor 28 and the new remainder 17,and apply the division lemma to get
28 = 17 x 1 + 11
We consider the new divisor 17 and the new remainder 11,and apply the division lemma to get
17 = 11 x 1 + 6
We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1243 and 6170 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(17,11) = HCF(28,17) = HCF(45,28) = HCF(1198,45) = HCF(1243,1198) = HCF(6170,1243) .
