HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 287, 1269 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 287, 1269 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 287, 1269 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 287, 1269 is 1.
HCF(287, 1269) = 1
HCF of 287, 1269 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 287, 1269 is 1.
Highest Common Factor of 287,1269 is 1
Step 1: Since 1269 > 287, we apply the division lemma to 1269 and 287, to get
1269 = 287 x 4 + 121
Step 2: Since the reminder 287 ≠ 0, we apply division lemma to 121 and 287, to get
287 = 121 x 2 + 45
Step 3: We consider the new divisor 121 and the new remainder 45, and apply the division lemma to get
121 = 45 x 2 + 31
We consider the new divisor 45 and the new remainder 31,and apply the division lemma to get
45 = 31 x 1 + 14
We consider the new divisor 31 and the new remainder 14,and apply the division lemma to get
31 = 14 x 2 + 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 287 and 1269 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(31,14) = HCF(45,31) = HCF(121,45) = HCF(287,121) = HCF(1269,287) .
