HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 442, 845, 794 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 442, 845, 794 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 442, 845, 794 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 442, 845, 794 is 1.
HCF(442, 845, 794) = 1
HCF of 442, 845, 794 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 442, 845, 794 is 1.
Highest Common Factor of 442,845,794 is 1
Step 1: Since 845 > 442, we apply the division lemma to 845 and 442, to get
845 = 442 x 1 + 403
Step 2: Since the reminder 442 ≠ 0, we apply division lemma to 403 and 442, to get
442 = 403 x 1 + 39
Step 3: We consider the new divisor 403 and the new remainder 39, and apply the division lemma to get
403 = 39 x 10 + 13
We consider the new divisor 39 and the new remainder 13, and apply the division lemma to get
39 = 13 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 442 and 845 is 13
Notice that 13 = HCF(39,13) = HCF(403,39) = HCF(442,403) = HCF(845,442) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 794 > 13, we apply the division lemma to 794 and 13, to get
794 = 13 x 61 + 1
Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 1 and 13, to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 13 and 794 is 1
Notice that 1 = HCF(13,1) = HCF(794,13) .
