HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 475, 847, 248 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 475, 847, 248 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 475, 847, 248 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 475, 847, 248 is 1.
HCF(475, 847, 248) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 475, 847, 248 is 1.
Step 1: Since 847 > 475, we apply the division lemma to 847 and 475, to get
847 = 475 x 1 + 372
Step 2: Since the reminder 475 ≠ 0, we apply division lemma to 372 and 475, to get
475 = 372 x 1 + 103
Step 3: We consider the new divisor 372 and the new remainder 103, and apply the division lemma to get
372 = 103 x 3 + 63
We consider the new divisor 103 and the new remainder 63,and apply the division lemma to get
103 = 63 x 1 + 40
We consider the new divisor 63 and the new remainder 40,and apply the division lemma to get
63 = 40 x 1 + 23
We consider the new divisor 40 and the new remainder 23,and apply the division lemma to get
40 = 23 x 1 + 17
We consider the new divisor 23 and the new remainder 17,and apply the division lemma to get
23 = 17 x 1 + 6
We consider the new divisor 17 and the new remainder 6,and apply the division lemma to get
17 = 6 x 2 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 475 and 847 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(17,6) = HCF(23,17) = HCF(40,23) = HCF(63,40) = HCF(103,63) = HCF(372,103) = HCF(475,372) = HCF(847,475) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 248 > 1, we apply the division lemma to 248 and 1, to get
248 = 1 x 248 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 248 is 1
Notice that 1 = HCF(248,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
