HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 829, 479, 69, 306 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 829, 479, 69, 306 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 829, 479, 69, 306 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 829, 479, 69, 306 is 1.
HCF(829, 479, 69, 306) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 829, 479, 69, 306 is 1.
Step 1: Since 829 > 479, we apply the division lemma to 829 and 479, to get
829 = 479 x 1 + 350
Step 2: Since the reminder 479 ≠ 0, we apply division lemma to 350 and 479, to get
479 = 350 x 1 + 129
Step 3: We consider the new divisor 350 and the new remainder 129, and apply the division lemma to get
350 = 129 x 2 + 92
We consider the new divisor 129 and the new remainder 92,and apply the division lemma to get
129 = 92 x 1 + 37
We consider the new divisor 92 and the new remainder 37,and apply the division lemma to get
92 = 37 x 2 + 18
We consider the new divisor 37 and the new remainder 18,and apply the division lemma to get
37 = 18 x 2 + 1
We consider the new divisor 18 and the new remainder 1,and apply the division lemma to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 829 and 479 is 1
Notice that 1 = HCF(18,1) = HCF(37,18) = HCF(92,37) = HCF(129,92) = HCF(350,129) = HCF(479,350) = HCF(829,479) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 69 > 1, we apply the division lemma to 69 and 1, to get
69 = 1 x 69 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 69 is 1
Notice that 1 = HCF(69,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 306 > 1, we apply the division lemma to 306 and 1, to get
306 = 1 x 306 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 306 is 1
Notice that 1 = HCF(306,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
