HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 346, 490, 458 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 346, 490, 458 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 346, 490, 458 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 346, 490, 458 is 2.
HCF(346, 490, 458) = 2
HCF of 346, 490, 458 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 346, 490, 458 is 2.
Highest Common Factor of 346,490,458 is 2
Step 1: Since 490 > 346, we apply the division lemma to 490 and 346, to get
490 = 346 x 1 + 144
Step 2: Since the reminder 346 ≠ 0, we apply division lemma to 144 and 346, to get
346 = 144 x 2 + 58
Step 3: We consider the new divisor 144 and the new remainder 58, and apply the division lemma to get
144 = 58 x 2 + 28
We consider the new divisor 58 and the new remainder 28,and apply the division lemma to get
58 = 28 x 2 + 2
We consider the new divisor 28 and the new remainder 2,and apply the division lemma to get
28 = 2 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 346 and 490 is 2
Notice that 2 = HCF(28,2) = HCF(58,28) = HCF(144,58) = HCF(346,144) = HCF(490,346) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 458 > 2, we apply the division lemma to 458 and 2, to get
458 = 2 x 229 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 458 is 2
Notice that 2 = HCF(458,2) .
