HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 795, 675, 29 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 795, 675, 29 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 795, 675, 29 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 795, 675, 29 is 1.
HCF(795, 675, 29) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 795, 675, 29 is 1.
Step 1: Since 795 > 675, we apply the division lemma to 795 and 675, to get
795 = 675 x 1 + 120
Step 2: Since the reminder 675 ≠ 0, we apply division lemma to 120 and 675, to get
675 = 120 x 5 + 75
Step 3: We consider the new divisor 120 and the new remainder 75, and apply the division lemma to get
120 = 75 x 1 + 45
We consider the new divisor 75 and the new remainder 45,and apply the division lemma to get
75 = 45 x 1 + 30
We consider the new divisor 45 and the new remainder 30,and apply the division lemma to get
45 = 30 x 1 + 15
We consider the new divisor 30 and the new remainder 15,and apply the division lemma to get
30 = 15 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 795 and 675 is 15
Notice that 15 = HCF(30,15) = HCF(45,30) = HCF(75,45) = HCF(120,75) = HCF(675,120) = HCF(795,675) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 29 > 15, we apply the division lemma to 29 and 15, to get
29 = 15 x 1 + 14
Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 14 and 15, to get
15 = 14 x 1 + 1
Step 3: We consider the new divisor 14 and the new remainder 1, and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 15 and 29 is 1
Notice that 1 = HCF(14,1) = HCF(15,14) = HCF(29,15) .
Here are some samples of HCF using Euclid's Algorithm calculations.
