HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 384, 820, 719 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 384, 820, 719 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 384, 820, 719 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 384, 820, 719 is 1.
HCF(384, 820, 719) = 1
HCF of 384, 820, 719 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 384, 820, 719 is 1.
Highest Common Factor of 384,820,719 is 1
Step 1: Since 820 > 384, we apply the division lemma to 820 and 384, to get
820 = 384 x 2 + 52
Step 2: Since the reminder 384 ≠ 0, we apply division lemma to 52 and 384, to get
384 = 52 x 7 + 20
Step 3: We consider the new divisor 52 and the new remainder 20, and apply the division lemma to get
52 = 20 x 2 + 12
We consider the new divisor 20 and the new remainder 12,and apply the division lemma to get
20 = 12 x 1 + 8
We consider the new divisor 12 and the new remainder 8,and apply the division lemma to get
12 = 8 x 1 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 384 and 820 is 4
Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(20,12) = HCF(52,20) = HCF(384,52) = HCF(820,384) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 719 > 4, we apply the division lemma to 719 and 4, to get
719 = 4 x 179 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 719 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(719,4) .
