HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 5145, 1173 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 5145, 1173 is 3 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 5145, 1173 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 5145, 1173 is 3.
HCF(5145, 1173) = 3
HCF of 5145, 1173 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 5145, 1173 is 3.
Highest Common Factor of 5145,1173 is 3
Step 1: Since 5145 > 1173, we apply the division lemma to 5145 and 1173, to get
5145 = 1173 x 4 + 453
Step 2: Since the reminder 1173 ≠ 0, we apply division lemma to 453 and 1173, to get
1173 = 453 x 2 + 267
Step 3: We consider the new divisor 453 and the new remainder 267, and apply the division lemma to get
453 = 267 x 1 + 186
We consider the new divisor 267 and the new remainder 186,and apply the division lemma to get
267 = 186 x 1 + 81
We consider the new divisor 186 and the new remainder 81,and apply the division lemma to get
186 = 81 x 2 + 24
We consider the new divisor 81 and the new remainder 24,and apply the division lemma to get
81 = 24 x 3 + 9
We consider the new divisor 24 and the new remainder 9,and apply the division lemma to get
24 = 9 x 2 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 5145 and 1173 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(24,9) = HCF(81,24) = HCF(186,81) = HCF(267,186) = HCF(453,267) = HCF(1173,453) = HCF(5145,1173) .
