HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 558, 758 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 558, 758 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 558, 758 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 558, 758 is 2.
HCF(558, 758) = 2
HCF of 558, 758 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 558, 758 is 2.
Highest Common Factor of 558,758 is 2
Step 1: Since 758 > 558, we apply the division lemma to 758 and 558, to get
758 = 558 x 1 + 200
Step 2: Since the reminder 558 ≠ 0, we apply division lemma to 200 and 558, to get
558 = 200 x 2 + 158
Step 3: We consider the new divisor 200 and the new remainder 158, and apply the division lemma to get
200 = 158 x 1 + 42
We consider the new divisor 158 and the new remainder 42,and apply the division lemma to get
158 = 42 x 3 + 32
We consider the new divisor 42 and the new remainder 32,and apply the division lemma to get
42 = 32 x 1 + 10
We consider the new divisor 32 and the new remainder 10,and apply the division lemma to get
32 = 10 x 3 + 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 558 and 758 is 2
Notice that 2 = HCF(10,2) = HCF(32,10) = HCF(42,32) = HCF(158,42) = HCF(200,158) = HCF(558,200) = HCF(758,558) .
