HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 808, 471, 786, 175 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 808, 471, 786, 175 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 808, 471, 786, 175 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 808, 471, 786, 175 is 1.
HCF(808, 471, 786, 175) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 808, 471, 786, 175 is 1.
Step 1: Since 808 > 471, we apply the division lemma to 808 and 471, to get
808 = 471 x 1 + 337
Step 2: Since the reminder 471 ≠ 0, we apply division lemma to 337 and 471, to get
471 = 337 x 1 + 134
Step 3: We consider the new divisor 337 and the new remainder 134, and apply the division lemma to get
337 = 134 x 2 + 69
We consider the new divisor 134 and the new remainder 69,and apply the division lemma to get
134 = 69 x 1 + 65
We consider the new divisor 69 and the new remainder 65,and apply the division lemma to get
69 = 65 x 1 + 4
We consider the new divisor 65 and the new remainder 4,and apply the division lemma to get
65 = 4 x 16 + 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 808 and 471 is 1
Notice that 1 = HCF(4,1) = HCF(65,4) = HCF(69,65) = HCF(134,69) = HCF(337,134) = HCF(471,337) = HCF(808,471) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 786 > 1, we apply the division lemma to 786 and 1, to get
786 = 1 x 786 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 786 is 1
Notice that 1 = HCF(786,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 175 > 1, we apply the division lemma to 175 and 1, to get
175 = 1 x 175 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 175 is 1
Notice that 1 = HCF(175,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
