HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 391, 7066, 1226 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 391, 7066, 1226 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 391, 7066, 1226 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 391, 7066, 1226 is 1.
HCF(391, 7066, 1226) = 1
HCF of 391, 7066, 1226 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 391, 7066, 1226 is 1.
Highest Common Factor of 391,7066,1226 is 1
Step 1: Since 7066 > 391, we apply the division lemma to 7066 and 391, to get
7066 = 391 x 18 + 28
Step 2: Since the reminder 391 ≠ 0, we apply division lemma to 28 and 391, to get
391 = 28 x 13 + 27
Step 3: We consider the new divisor 28 and the new remainder 27, and apply the division lemma to get
28 = 27 x 1 + 1
We consider the new divisor 27 and the new remainder 1, and apply the division lemma to get
27 = 1 x 27 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 391 and 7066 is 1
Notice that 1 = HCF(27,1) = HCF(28,27) = HCF(391,28) = HCF(7066,391) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 1226 > 1, we apply the division lemma to 1226 and 1, to get
1226 = 1 x 1226 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 1226 is 1
Notice that 1 = HCF(1226,1) .
