HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 438, 48484 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 438, 48484 is 2 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 438, 48484 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 438, 48484 is 2.
HCF(438, 48484) = 2
HCF of 438, 48484 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 438, 48484 is 2.
Highest Common Factor of 438,48484 is 2
Step 1: Since 48484 > 438, we apply the division lemma to 48484 and 438, to get
48484 = 438 x 110 + 304
Step 2: Since the reminder 438 ≠ 0, we apply division lemma to 304 and 438, to get
438 = 304 x 1 + 134
Step 3: We consider the new divisor 304 and the new remainder 134, and apply the division lemma to get
304 = 134 x 2 + 36
We consider the new divisor 134 and the new remainder 36,and apply the division lemma to get
134 = 36 x 3 + 26
We consider the new divisor 36 and the new remainder 26,and apply the division lemma to get
36 = 26 x 1 + 10
We consider the new divisor 26 and the new remainder 10,and apply the division lemma to get
26 = 10 x 2 + 6
We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get
10 = 6 x 1 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 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 438 and 48484 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(26,10) = HCF(36,26) = HCF(134,36) = HCF(304,134) = HCF(438,304) = HCF(48484,438) .
