HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 814, 444, 669 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 814, 444, 669 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 814, 444, 669 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 814, 444, 669 is 1.
HCF(814, 444, 669) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 814, 444, 669 is 1.
Step 1: Since 814 > 444, we apply the division lemma to 814 and 444, to get
814 = 444 x 1 + 370
Step 2: Since the reminder 444 ≠ 0, we apply division lemma to 370 and 444, to get
444 = 370 x 1 + 74
Step 3: We consider the new divisor 370 and the new remainder 74, and apply the division lemma to get
370 = 74 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 74, the HCF of 814 and 444 is 74
Notice that 74 = HCF(370,74) = HCF(444,370) = HCF(814,444) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 669 > 74, we apply the division lemma to 669 and 74, to get
669 = 74 x 9 + 3
Step 2: Since the reminder 74 ≠ 0, we apply division lemma to 3 and 74, to get
74 = 3 x 24 + 2
Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get
3 = 2 x 1 + 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 74 and 669 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(74,3) = HCF(669,74) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
