HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 538, 438, 935 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 538, 438, 935 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 538, 438, 935 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 538, 438, 935 is 1.
HCF(538, 438, 935) = 1
HCF of 538, 438, 935 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 538, 438, 935 is 1.
Highest Common Factor of 538,438,935 is 1
Step 1: Since 538 > 438, we apply the division lemma to 538 and 438, to get
538 = 438 x 1 + 100
Step 2: Since the reminder 438 ≠ 0, we apply division lemma to 100 and 438, to get
438 = 100 x 4 + 38
Step 3: We consider the new divisor 100 and the new remainder 38, and apply the division lemma to get
100 = 38 x 2 + 24
We consider the new divisor 38 and the new remainder 24,and apply the division lemma to get
38 = 24 x 1 + 14
We consider the new divisor 24 and the new remainder 14,and apply the division lemma to get
24 = 14 x 1 + 10
We consider the new divisor 14 and the new remainder 10,and apply the division lemma to get
14 = 10 x 1 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 538 and 438 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(14,10) = HCF(24,14) = HCF(38,24) = HCF(100,38) = HCF(438,100) = HCF(538,438) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 935 > 2, we apply the division lemma to 935 and 2, to get
935 = 2 x 467 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 935 is 1
Notice that 1 = HCF(2,1) = HCF(935,2) .
