HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 471, 868, 13, 255 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 471, 868, 13, 255 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 471, 868, 13, 255 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 471, 868, 13, 255 is 1.
HCF(471, 868, 13, 255) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 471, 868, 13, 255 is 1.
Step 1: Since 868 > 471, we apply the division lemma to 868 and 471, to get
868 = 471 x 1 + 397
Step 2: Since the reminder 471 ≠ 0, we apply division lemma to 397 and 471, to get
471 = 397 x 1 + 74
Step 3: We consider the new divisor 397 and the new remainder 74, and apply the division lemma to get
397 = 74 x 5 + 27
We consider the new divisor 74 and the new remainder 27,and apply the division lemma to get
74 = 27 x 2 + 20
We consider the new divisor 27 and the new remainder 20,and apply the division lemma to get
27 = 20 x 1 + 7
We consider the new divisor 20 and the new remainder 7,and apply the division lemma to get
20 = 7 x 2 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 471 and 868 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(20,7) = HCF(27,20) = HCF(74,27) = HCF(397,74) = HCF(471,397) = HCF(868,471) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 13 > 1, we apply the division lemma to 13 and 1, to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 13 is 1
Notice that 1 = HCF(13,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 255 > 1, we apply the division lemma to 255 and 1, to get
255 = 1 x 255 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 255 is 1
Notice that 1 = HCF(255,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
