HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 29, 56, 86, 638 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 29, 56, 86, 638 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 29, 56, 86, 638 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 29, 56, 86, 638 is 1.
HCF(29, 56, 86, 638) = 1
HCF of 29, 56, 86, 638 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 29, 56, 86, 638 is 1.
Highest Common Factor of 29,56,86,638 is 1
Step 1: Since 56 > 29, we apply the division lemma to 56 and 29, to get
56 = 29 x 1 + 27
Step 2: Since the reminder 29 ≠ 0, we apply division lemma to 27 and 29, to get
29 = 27 x 1 + 2
Step 3: We consider the new divisor 27 and the new remainder 2, and apply the division lemma to get
27 = 2 x 13 + 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 29 and 56 is 1
Notice that 1 = HCF(2,1) = HCF(27,2) = HCF(29,27) = HCF(56,29) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 86 > 1, we apply the division lemma to 86 and 1, to get
86 = 1 x 86 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 86 is 1
Notice that 1 = HCF(86,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 638 > 1, we apply the division lemma to 638 and 1, to get
638 = 1 x 638 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 638 is 1
Notice that 1 = HCF(638,1) .
