HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 558, 679 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 558, 679 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 558, 679 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, 679 is 1.
HCF(558, 679) = 1
HCF of 558, 679 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, 679 is 1.
Highest Common Factor of 558,679 is 1
Step 1: Since 679 > 558, we apply the division lemma to 679 and 558, to get
679 = 558 x 1 + 121
Step 2: Since the reminder 558 ≠ 0, we apply division lemma to 121 and 558, to get
558 = 121 x 4 + 74
Step 3: We consider the new divisor 121 and the new remainder 74, and apply the division lemma to get
121 = 74 x 1 + 47
We consider the new divisor 74 and the new remainder 47,and apply the division lemma to get
74 = 47 x 1 + 27
We consider the new divisor 47 and the new remainder 27,and apply the division lemma to get
47 = 27 x 1 + 20
We consider the new divisor 27 and the new remainder 20,and apply the division lemma to get
27 = 20 x 1 + 7
We consider the new divisor 20 and the new remainder 7,and apply the division lemma to get
20 = 7 x 2 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 558 and 679 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(20,7) = HCF(27,20) = HCF(47,27) = HCF(74,47) = HCF(121,74) = HCF(558,121) = HCF(679,558) .
