HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 438, 608 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 438, 608 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, 608 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, 608 is 2.
HCF(438, 608) = 2
HCF of 438, 608 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, 608 is 2.
Highest Common Factor of 438,608 is 2
Step 1: Since 608 > 438, we apply the division lemma to 608 and 438, to get
608 = 438 x 1 + 170
Step 2: Since the reminder 438 ≠ 0, we apply division lemma to 170 and 438, to get
438 = 170 x 2 + 98
Step 3: We consider the new divisor 170 and the new remainder 98, and apply the division lemma to get
170 = 98 x 1 + 72
We consider the new divisor 98 and the new remainder 72,and apply the division lemma to get
98 = 72 x 1 + 26
We consider the new divisor 72 and the new remainder 26,and apply the division lemma to get
72 = 26 x 2 + 20
We consider the new divisor 26 and the new remainder 20,and apply the division lemma to get
26 = 20 x 1 + 6
We consider the new divisor 20 and the new remainder 6,and apply the division lemma to get
20 = 6 x 3 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 438 and 608 is 2
Notice that 2 = HCF(6,2) = HCF(20,6) = HCF(26,20) = HCF(72,26) = HCF(98,72) = HCF(170,98) = HCF(438,170) = HCF(608,438) .
