HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1298, 953 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1298, 953 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 1298, 953 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 1298, 953 is 1.
HCF(1298, 953) = 1
HCF of 1298, 953 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1298, 953 is 1.
Highest Common Factor of 1298,953 is 1
Step 1: Since 1298 > 953, we apply the division lemma to 1298 and 953, to get
1298 = 953 x 1 + 345
Step 2: Since the reminder 953 ≠ 0, we apply division lemma to 345 and 953, to get
953 = 345 x 2 + 263
Step 3: We consider the new divisor 345 and the new remainder 263, and apply the division lemma to get
345 = 263 x 1 + 82
We consider the new divisor 263 and the new remainder 82,and apply the division lemma to get
263 = 82 x 3 + 17
We consider the new divisor 82 and the new remainder 17,and apply the division lemma to get
82 = 17 x 4 + 14
We consider the new divisor 17 and the new remainder 14,and apply the division lemma to get
17 = 14 x 1 + 3
We consider the new divisor 14 and the new remainder 3,and apply the division lemma to get
14 = 3 x 4 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1298 and 953 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(17,14) = HCF(82,17) = HCF(263,82) = HCF(345,263) = HCF(953,345) = HCF(1298,953) .
