HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 125, 575, 125, 38 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 125, 575, 125, 38 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 125, 575, 125, 38 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 125, 575, 125, 38 is 1.
HCF(125, 575, 125, 38) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 125, 575, 125, 38 is 1.
Step 1: Since 575 > 125, we apply the division lemma to 575 and 125, to get
575 = 125 x 4 + 75
Step 2: Since the reminder 125 ≠ 0, we apply division lemma to 75 and 125, to get
125 = 75 x 1 + 50
Step 3: We consider the new divisor 75 and the new remainder 50, and apply the division lemma to get
75 = 50 x 1 + 25
We consider the new divisor 50 and the new remainder 25, and apply the division lemma to get
50 = 25 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 25, the HCF of 125 and 575 is 25
Notice that 25 = HCF(50,25) = HCF(75,50) = HCF(125,75) = HCF(575,125) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 125 > 25, we apply the division lemma to 125 and 25, to get
125 = 25 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 25, the HCF of 25 and 125 is 25
Notice that 25 = HCF(125,25) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 38 > 25, we apply the division lemma to 38 and 25, to get
38 = 25 x 1 + 13
Step 2: Since the reminder 25 ≠ 0, we apply division lemma to 13 and 25, to get
25 = 13 x 1 + 12
Step 3: We consider the new divisor 13 and the new remainder 12, and apply the division lemma to get
13 = 12 x 1 + 1
We consider the new divisor 12 and the new remainder 1, and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 25 and 38 is 1
Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(25,13) = HCF(38,25) .
Here are some samples of HCF using Euclid's Algorithm calculations.
