HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 512, 889, 721 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 512, 889, 721 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 512, 889, 721 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 512, 889, 721 is 1.
HCF(512, 889, 721) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 512, 889, 721 is 1.
Step 1: Since 889 > 512, we apply the division lemma to 889 and 512, to get
889 = 512 x 1 + 377
Step 2: Since the reminder 512 ≠ 0, we apply division lemma to 377 and 512, to get
512 = 377 x 1 + 135
Step 3: We consider the new divisor 377 and the new remainder 135, and apply the division lemma to get
377 = 135 x 2 + 107
We consider the new divisor 135 and the new remainder 107,and apply the division lemma to get
135 = 107 x 1 + 28
We consider the new divisor 107 and the new remainder 28,and apply the division lemma to get
107 = 28 x 3 + 23
We consider the new divisor 28 and the new remainder 23,and apply the division lemma to get
28 = 23 x 1 + 5
We consider the new divisor 23 and the new remainder 5,and apply the division lemma to get
23 = 5 x 4 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
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 512 and 889 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(23,5) = HCF(28,23) = HCF(107,28) = HCF(135,107) = HCF(377,135) = HCF(512,377) = HCF(889,512) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 721 > 1, we apply the division lemma to 721 and 1, to get
721 = 1 x 721 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 721 is 1
Notice that 1 = HCF(721,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
