HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 458, 318, 474 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 458, 318, 474 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 458, 318, 474 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, 318, 474 is 2.
HCF(458, 318, 474) = 2
HCF of 458, 318, 474 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, 318, 474 is 2.
Highest Common Factor of 458,318,474 is 2
Step 1: Since 458 > 318, we apply the division lemma to 458 and 318, to get
458 = 318 x 1 + 140
Step 2: Since the reminder 318 ≠ 0, we apply division lemma to 140 and 318, to get
318 = 140 x 2 + 38
Step 3: We consider the new divisor 140 and the new remainder 38, and apply the division lemma to get
140 = 38 x 3 + 26
We consider the new divisor 38 and the new remainder 26,and apply the division lemma to get
38 = 26 x 1 + 12
We consider the new divisor 26 and the new remainder 12,and apply the division lemma to get
26 = 12 x 2 + 2
We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get
12 = 2 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 458 and 318 is 2
Notice that 2 = HCF(12,2) = HCF(26,12) = HCF(38,26) = HCF(140,38) = HCF(318,140) = HCF(458,318) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 474 > 2, we apply the division lemma to 474 and 2, to get
474 = 2 x 237 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 474 is 2
Notice that 2 = HCF(474,2) .
