HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 845, 330, 38, 575 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 845, 330, 38, 575 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 845, 330, 38, 575 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 845, 330, 38, 575 is 1.
HCF(845, 330, 38, 575) = 1
HCF of 845, 330, 38, 575 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 845, 330, 38, 575 is 1.
Highest Common Factor of 845,330,38,575 is 1
Step 1: Since 845 > 330, we apply the division lemma to 845 and 330, to get
845 = 330 x 2 + 185
Step 2: Since the reminder 330 ≠ 0, we apply division lemma to 185 and 330, to get
330 = 185 x 1 + 145
Step 3: We consider the new divisor 185 and the new remainder 145, and apply the division lemma to get
185 = 145 x 1 + 40
We consider the new divisor 145 and the new remainder 40,and apply the division lemma to get
145 = 40 x 3 + 25
We consider the new divisor 40 and the new remainder 25,and apply the division lemma to get
40 = 25 x 1 + 15
We consider the new divisor 25 and the new remainder 15,and apply the division lemma to get
25 = 15 x 1 + 10
We consider the new divisor 15 and the new remainder 10,and apply the division lemma to get
15 = 10 x 1 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 845 and 330 is 5
Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(25,15) = HCF(40,25) = HCF(145,40) = HCF(185,145) = HCF(330,185) = HCF(845,330) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 38 > 5, we apply the division lemma to 38 and 5, to get
38 = 5 x 7 + 3
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get
5 = 3 x 1 + 2
Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get
3 = 2 x 1 + 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 5 and 38 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(38,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 575 > 1, we apply the division lemma to 575 and 1, to get
575 = 1 x 575 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 575 is 1
Notice that 1 = HCF(575,1) .
