HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 438, 908 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 438, 908 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, 908 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, 908 is 2.
HCF(438, 908) = 2
HCF of 438, 908 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, 908 is 2.
Highest Common Factor of 438,908 is 2
Step 1: Since 908 > 438, we apply the division lemma to 908 and 438, to get
908 = 438 x 2 + 32
Step 2: Since the reminder 438 ≠ 0, we apply division lemma to 32 and 438, to get
438 = 32 x 13 + 22
Step 3: We consider the new divisor 32 and the new remainder 22, and apply the division lemma to get
32 = 22 x 1 + 10
We consider the new divisor 22 and the new remainder 10,and apply the division lemma to get
22 = 10 x 2 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 438 and 908 is 2
Notice that 2 = HCF(10,2) = HCF(22,10) = HCF(32,22) = HCF(438,32) = HCF(908,438) .
