HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 72, 29, 39, 86 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 72, 29, 39, 86 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 72, 29, 39, 86 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 72, 29, 39, 86 is 1.
HCF(72, 29, 39, 86) = 1
HCF of 72, 29, 39, 86 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 72, 29, 39, 86 is 1.
Highest Common Factor of 72,29,39,86 is 1
Step 1: Since 72 > 29, we apply the division lemma to 72 and 29, to get
72 = 29 x 2 + 14
Step 2: Since the reminder 29 ≠ 0, we apply division lemma to 14 and 29, to get
29 = 14 x 2 + 1
Step 3: We consider the new divisor 14 and the new remainder 1, and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 72 and 29 is 1
Notice that 1 = HCF(14,1) = HCF(29,14) = HCF(72,29) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 39 > 1, we apply the division lemma to 39 and 1, to get
39 = 1 x 39 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 39 is 1
Notice that 1 = HCF(39,1) .
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) .
