HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 906, 638, 427 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 906, 638, 427 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 906, 638, 427 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 906, 638, 427 is 1.
HCF(906, 638, 427) = 1
HCF of 906, 638, 427 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 906, 638, 427 is 1.
Highest Common Factor of 906,638,427 is 1
Step 1: Since 906 > 638, we apply the division lemma to 906 and 638, to get
906 = 638 x 1 + 268
Step 2: Since the reminder 638 ≠ 0, we apply division lemma to 268 and 638, to get
638 = 268 x 2 + 102
Step 3: We consider the new divisor 268 and the new remainder 102, and apply the division lemma to get
268 = 102 x 2 + 64
We consider the new divisor 102 and the new remainder 64,and apply the division lemma to get
102 = 64 x 1 + 38
We consider the new divisor 64 and the new remainder 38,and apply the division lemma to get
64 = 38 x 1 + 26
We consider the new divisor 38 and the new remainder 26,and apply the division lemma to get
38 = 26 x 1 + 12
We consider the new divisor 26 and the new remainder 12,and apply the division lemma to get
26 = 12 x 2 + 2
We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get
12 = 2 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 906 and 638 is 2
Notice that 2 = HCF(12,2) = HCF(26,12) = HCF(38,26) = HCF(64,38) = HCF(102,64) = HCF(268,102) = HCF(638,268) = HCF(906,638) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 427 > 2, we apply the division lemma to 427 and 2, to get
427 = 2 x 213 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 427 is 1
Notice that 1 = HCF(2,1) = HCF(427,2) .
