HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 146, 803, 917 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 146, 803, 917 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 146, 803, 917 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 146, 803, 917 is 1.
HCF(146, 803, 917) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 146, 803, 917 is 1.
Step 1: Since 803 > 146, we apply the division lemma to 803 and 146, to get
803 = 146 x 5 + 73
Step 2: Since the reminder 146 ≠ 0, we apply division lemma to 73 and 146, to get
146 = 73 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 73, the HCF of 146 and 803 is 73
Notice that 73 = HCF(146,73) = HCF(803,146) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 917 > 73, we apply the division lemma to 917 and 73, to get
917 = 73 x 12 + 41
Step 2: Since the reminder 73 ≠ 0, we apply division lemma to 41 and 73, to get
73 = 41 x 1 + 32
Step 3: We consider the new divisor 41 and the new remainder 32, and apply the division lemma to get
41 = 32 x 1 + 9
We consider the new divisor 32 and the new remainder 9,and apply the division lemma to get
32 = 9 x 3 + 5
We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get
9 = 5 x 1 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 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 73 and 917 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(32,9) = HCF(41,32) = HCF(73,41) = HCF(917,73) .
Here are some samples of HCF using Euclid's Algorithm calculations.
