HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 432, 645, 104, 329 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 432, 645, 104, 329 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 432, 645, 104, 329 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 432, 645, 104, 329 is 1.
HCF(432, 645, 104, 329) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 432, 645, 104, 329 is 1.
Step 1: Since 645 > 432, we apply the division lemma to 645 and 432, to get
645 = 432 x 1 + 213
Step 2: Since the reminder 432 ≠ 0, we apply division lemma to 213 and 432, to get
432 = 213 x 2 + 6
Step 3: We consider the new divisor 213 and the new remainder 6, and apply the division lemma to get
213 = 6 x 35 + 3
We consider the new divisor 6 and the new remainder 3, and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 432 and 645 is 3
Notice that 3 = HCF(6,3) = HCF(213,6) = HCF(432,213) = HCF(645,432) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 104 > 3, we apply the division lemma to 104 and 3, to get
104 = 3 x 34 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 104 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(104,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 329 > 1, we apply the division lemma to 329 and 1, to get
329 = 1 x 329 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 329 is 1
Notice that 1 = HCF(329,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
