HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 458, 556, 679 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 458, 556, 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 458, 556, 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 458, 556, 679 is 1.
HCF(458, 556, 679) = 1
HCF of 458, 556, 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 458, 556, 679 is 1.
Highest Common Factor of 458,556,679 is 1
Step 1: Since 556 > 458, we apply the division lemma to 556 and 458, to get
556 = 458 x 1 + 98
Step 2: Since the reminder 458 ≠ 0, we apply division lemma to 98 and 458, to get
458 = 98 x 4 + 66
Step 3: We consider the new divisor 98 and the new remainder 66, and apply the division lemma to get
98 = 66 x 1 + 32
We consider the new divisor 66 and the new remainder 32,and apply the division lemma to get
66 = 32 x 2 + 2
We consider the new divisor 32 and the new remainder 2,and apply the division lemma to get
32 = 2 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 458 and 556 is 2
Notice that 2 = HCF(32,2) = HCF(66,32) = HCF(98,66) = HCF(458,98) = HCF(556,458) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 679 > 2, we apply the division lemma to 679 and 2, to get
679 = 2 x 339 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 679 is 1
Notice that 1 = HCF(2,1) = HCF(679,2) .
