HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 747, 857, 572, 258 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 747, 857, 572, 258 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 747, 857, 572, 258 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 747, 857, 572, 258 is 1.
HCF(747, 857, 572, 258) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 747, 857, 572, 258 is 1.
Step 1: Since 857 > 747, we apply the division lemma to 857 and 747, to get
857 = 747 x 1 + 110
Step 2: Since the reminder 747 ≠ 0, we apply division lemma to 110 and 747, to get
747 = 110 x 6 + 87
Step 3: We consider the new divisor 110 and the new remainder 87, and apply the division lemma to get
110 = 87 x 1 + 23
We consider the new divisor 87 and the new remainder 23,and apply the division lemma to get
87 = 23 x 3 + 18
We consider the new divisor 23 and the new remainder 18,and apply the division lemma to get
23 = 18 x 1 + 5
We consider the new divisor 18 and the new remainder 5,and apply the division lemma to get
18 = 5 x 3 + 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 747 and 857 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(23,18) = HCF(87,23) = HCF(110,87) = HCF(747,110) = HCF(857,747) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 572 > 1, we apply the division lemma to 572 and 1, to get
572 = 1 x 572 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 572 is 1
Notice that 1 = HCF(572,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 258 > 1, we apply the division lemma to 258 and 1, to get
258 = 1 x 258 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 258 is 1
Notice that 1 = HCF(258,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
