HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 4358, 638 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 4358, 638 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 4358, 638 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 4358, 638 is 2.
HCF(4358, 638) = 2
HCF of 4358, 638 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 4358, 638 is 2.
Highest Common Factor of 4358,638 is 2
Step 1: Since 4358 > 638, we apply the division lemma to 4358 and 638, to get
4358 = 638 x 6 + 530
Step 2: Since the reminder 638 ≠ 0, we apply division lemma to 530 and 638, to get
638 = 530 x 1 + 108
Step 3: We consider the new divisor 530 and the new remainder 108, and apply the division lemma to get
530 = 108 x 4 + 98
We consider the new divisor 108 and the new remainder 98,and apply the division lemma to get
108 = 98 x 1 + 10
We consider the new divisor 98 and the new remainder 10,and apply the division lemma to get
98 = 10 x 9 + 8
We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get
10 = 8 x 1 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4358 and 638 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(98,10) = HCF(108,98) = HCF(530,108) = HCF(638,530) = HCF(4358,638) .
