HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1155, 9957 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 1155, 9957 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 1155, 9957 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 1155, 9957 is 3.
HCF(1155, 9957) = 3
HCF of 1155, 9957 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1155, 9957 is 3.
Highest Common Factor of 1155,9957 is 3
Step 1: Since 9957 > 1155, we apply the division lemma to 9957 and 1155, to get
9957 = 1155 x 8 + 717
Step 2: Since the reminder 1155 ≠ 0, we apply division lemma to 717 and 1155, to get
1155 = 717 x 1 + 438
Step 3: We consider the new divisor 717 and the new remainder 438, and apply the division lemma to get
717 = 438 x 1 + 279
We consider the new divisor 438 and the new remainder 279,and apply the division lemma to get
438 = 279 x 1 + 159
We consider the new divisor 279 and the new remainder 159,and apply the division lemma to get
279 = 159 x 1 + 120
We consider the new divisor 159 and the new remainder 120,and apply the division lemma to get
159 = 120 x 1 + 39
We consider the new divisor 120 and the new remainder 39,and apply the division lemma to get
120 = 39 x 3 + 3
We consider the new divisor 39 and the new remainder 3,and apply the division lemma to get
39 = 3 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 1155 and 9957 is 3
Notice that 3 = HCF(39,3) = HCF(120,39) = HCF(159,120) = HCF(279,159) = HCF(438,279) = HCF(717,438) = HCF(1155,717) = HCF(9957,1155) .
