HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 247, 178, 885 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 247, 178, 885 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 247, 178, 885 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 247, 178, 885 is 1.
HCF(247, 178, 885) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 247, 178, 885 is 1.
Step 1: Since 247 > 178, we apply the division lemma to 247 and 178, to get
247 = 178 x 1 + 69
Step 2: Since the reminder 178 ≠ 0, we apply division lemma to 69 and 178, to get
178 = 69 x 2 + 40
Step 3: We consider the new divisor 69 and the new remainder 40, and apply the division lemma to get
69 = 40 x 1 + 29
We consider the new divisor 40 and the new remainder 29,and apply the division lemma to get
40 = 29 x 1 + 11
We consider the new divisor 29 and the new remainder 11,and apply the division lemma to get
29 = 11 x 2 + 7
We consider the new divisor 11 and the new remainder 7,and apply the division lemma to get
11 = 7 x 1 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
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 247 and 178 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(29,11) = HCF(40,29) = HCF(69,40) = HCF(178,69) = HCF(247,178) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 885 > 1, we apply the division lemma to 885 and 1, to get
885 = 1 x 885 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 885 is 1
Notice that 1 = HCF(885,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
