HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 5151, 8503, 47685 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 5151, 8503, 47685 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 5151, 8503, 47685 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 5151, 8503, 47685 is 1.
HCF(5151, 8503, 47685) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 5151, 8503, 47685 is 1.
Step 1: Since 8503 > 5151, we apply the division lemma to 8503 and 5151, to get
8503 = 5151 x 1 + 3352
Step 2: Since the reminder 5151 ≠ 0, we apply division lemma to 3352 and 5151, to get
5151 = 3352 x 1 + 1799
Step 3: We consider the new divisor 3352 and the new remainder 1799, and apply the division lemma to get
3352 = 1799 x 1 + 1553
We consider the new divisor 1799 and the new remainder 1553,and apply the division lemma to get
1799 = 1553 x 1 + 246
We consider the new divisor 1553 and the new remainder 246,and apply the division lemma to get
1553 = 246 x 6 + 77
We consider the new divisor 246 and the new remainder 77,and apply the division lemma to get
246 = 77 x 3 + 15
We consider the new divisor 77 and the new remainder 15,and apply the division lemma to get
77 = 15 x 5 + 2
We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get
15 = 2 x 7 + 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 5151 and 8503 is 1
Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(77,15) = HCF(246,77) = HCF(1553,246) = HCF(1799,1553) = HCF(3352,1799) = HCF(5151,3352) = HCF(8503,5151) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 47685 > 1, we apply the division lemma to 47685 and 1, to get
47685 = 1 x 47685 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 47685 is 1
Notice that 1 = HCF(47685,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
