HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 426, 687, 341 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 426, 687, 341 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 426, 687, 341 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 426, 687, 341 is 1.
HCF(426, 687, 341) = 1
HCF of 426, 687, 341 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 426, 687, 341 is 1.
Highest Common Factor of 426,687,341 is 1
Step 1: Since 687 > 426, we apply the division lemma to 687 and 426, to get
687 = 426 x 1 + 261
Step 2: Since the reminder 426 ≠ 0, we apply division lemma to 261 and 426, to get
426 = 261 x 1 + 165
Step 3: We consider the new divisor 261 and the new remainder 165, and apply the division lemma to get
261 = 165 x 1 + 96
We consider the new divisor 165 and the new remainder 96,and apply the division lemma to get
165 = 96 x 1 + 69
We consider the new divisor 96 and the new remainder 69,and apply the division lemma to get
96 = 69 x 1 + 27
We consider the new divisor 69 and the new remainder 27,and apply the division lemma to get
69 = 27 x 2 + 15
We consider the new divisor 27 and the new remainder 15,and apply the division lemma to get
27 = 15 x 1 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 426 and 687 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(27,15) = HCF(69,27) = HCF(96,69) = HCF(165,96) = HCF(261,165) = HCF(426,261) = HCF(687,426) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 341 > 3, we apply the division lemma to 341 and 3, to get
341 = 3 x 113 + 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 341 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(341,3) .
