HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1269, 5455 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1269, 5455 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 1269, 5455 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 1269, 5455 is 1.
HCF(1269, 5455) = 1
HCF of 1269, 5455 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1269, 5455 is 1.
Highest Common Factor of 1269,5455 is 1
Step 1: Since 5455 > 1269, we apply the division lemma to 5455 and 1269, to get
5455 = 1269 x 4 + 379
Step 2: Since the reminder 1269 ≠ 0, we apply division lemma to 379 and 1269, to get
1269 = 379 x 3 + 132
Step 3: We consider the new divisor 379 and the new remainder 132, and apply the division lemma to get
379 = 132 x 2 + 115
We consider the new divisor 132 and the new remainder 115,and apply the division lemma to get
132 = 115 x 1 + 17
We consider the new divisor 115 and the new remainder 17,and apply the division lemma to get
115 = 17 x 6 + 13
We consider the new divisor 17 and the new remainder 13,and apply the division lemma to get
17 = 13 x 1 + 4
We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get
13 = 4 x 3 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1269 and 5455 is 1
Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(17,13) = HCF(115,17) = HCF(132,115) = HCF(379,132) = HCF(1269,379) = HCF(5455,1269) .
