HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 438, 587 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 438, 587 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 438, 587 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, 587 is 1.
HCF(438, 587) = 1
HCF of 438, 587 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, 587 is 1.
Highest Common Factor of 438,587 is 1
Step 1: Since 587 > 438, we apply the division lemma to 587 and 438, to get
587 = 438 x 1 + 149
Step 2: Since the reminder 438 ≠ 0, we apply division lemma to 149 and 438, to get
438 = 149 x 2 + 140
Step 3: We consider the new divisor 149 and the new remainder 140, and apply the division lemma to get
149 = 140 x 1 + 9
We consider the new divisor 140 and the new remainder 9,and apply the division lemma to get
140 = 9 x 15 + 5
We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get
9 = 5 x 1 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 438 and 587 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(140,9) = HCF(149,140) = HCF(438,149) = HCF(587,438) .
