HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 627, 9478, 9663 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 627, 9478, 9663 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 627, 9478, 9663 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 627, 9478, 9663 is 1.
HCF(627, 9478, 9663) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 627, 9478, 9663 is 1.
Step 1: Since 9478 > 627, we apply the division lemma to 9478 and 627, to get
9478 = 627 x 15 + 73
Step 2: Since the reminder 627 ≠ 0, we apply division lemma to 73 and 627, to get
627 = 73 x 8 + 43
Step 3: We consider the new divisor 73 and the new remainder 43, and apply the division lemma to get
73 = 43 x 1 + 30
We consider the new divisor 43 and the new remainder 30,and apply the division lemma to get
43 = 30 x 1 + 13
We consider the new divisor 30 and the new remainder 13,and apply the division lemma to get
30 = 13 x 2 + 4
We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get
13 = 4 x 3 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 627 and 9478 is 1
Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(30,13) = HCF(43,30) = HCF(73,43) = HCF(627,73) = HCF(9478,627) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 9663 > 1, we apply the division lemma to 9663 and 1, to get
9663 = 1 x 9663 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 9663 is 1
Notice that 1 = HCF(9663,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
