HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 172, 105, 110, 794 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 172, 105, 110, 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 172, 105, 110, 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 172, 105, 110, 794 is 1.
HCF(172, 105, 110, 794) = 1
HCF of 172, 105, 110, 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 172, 105, 110, 794 is 1.
Highest Common Factor of 172,105,110,794 is 1
Step 1: Since 172 > 105, we apply the division lemma to 172 and 105, to get
172 = 105 x 1 + 67
Step 2: Since the reminder 105 ≠ 0, we apply division lemma to 67 and 105, to get
105 = 67 x 1 + 38
Step 3: We consider the new divisor 67 and the new remainder 38, and apply the division lemma to get
67 = 38 x 1 + 29
We consider the new divisor 38 and the new remainder 29,and apply the division lemma to get
38 = 29 x 1 + 9
We consider the new divisor 29 and the new remainder 9,and apply the division lemma to get
29 = 9 x 3 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 1
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 172 and 105 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(29,9) = HCF(38,29) = HCF(67,38) = HCF(105,67) = HCF(172,105) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 110 > 1, we apply the division lemma to 110 and 1, to get
110 = 1 x 110 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 110 is 1
Notice that 1 = HCF(110,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 794 > 1, we apply the division lemma to 794 and 1, to get
794 = 1 x 794 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 794 is 1
Notice that 1 = HCF(794,1) .
