HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1286, 955 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1286, 955 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 1286, 955 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 1286, 955 is 1.
HCF(1286, 955) = 1
HCF of 1286, 955 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1286, 955 is 1.
Highest Common Factor of 1286,955 is 1
Step 1: Since 1286 > 955, we apply the division lemma to 1286 and 955, to get
1286 = 955 x 1 + 331
Step 2: Since the reminder 955 ≠ 0, we apply division lemma to 331 and 955, to get
955 = 331 x 2 + 293
Step 3: We consider the new divisor 331 and the new remainder 293, and apply the division lemma to get
331 = 293 x 1 + 38
We consider the new divisor 293 and the new remainder 38,and apply the division lemma to get
293 = 38 x 7 + 27
We consider the new divisor 38 and the new remainder 27,and apply the division lemma to get
38 = 27 x 1 + 11
We consider the new divisor 27 and the new remainder 11,and apply the division lemma to get
27 = 11 x 2 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 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 1286 and 955 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(27,11) = HCF(38,27) = HCF(293,38) = HCF(331,293) = HCF(955,331) = HCF(1286,955) .
