HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 459, 606, 278, 86 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 459, 606, 278, 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 459, 606, 278, 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 459, 606, 278, 86 is 1.
HCF(459, 606, 278, 86) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 459, 606, 278, 86 is 1.
Step 1: Since 606 > 459, we apply the division lemma to 606 and 459, to get
606 = 459 x 1 + 147
Step 2: Since the reminder 459 ≠ 0, we apply division lemma to 147 and 459, to get
459 = 147 x 3 + 18
Step 3: We consider the new divisor 147 and the new remainder 18, and apply the division lemma to get
147 = 18 x 8 + 3
We consider the new divisor 18 and the new remainder 3, and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 459 and 606 is 3
Notice that 3 = HCF(18,3) = HCF(147,18) = HCF(459,147) = HCF(606,459) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 278 > 3, we apply the division lemma to 278 and 3, to get
278 = 3 x 92 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 278 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(278,3) .
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) .
Here are some samples of HCF using Euclid's Algorithm calculations.
