HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 490, 355, 514 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 490, 355, 514 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 490, 355, 514 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 490, 355, 514 is 1.
HCF(490, 355, 514) = 1
HCF of 490, 355, 514 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 490, 355, 514 is 1.
Highest Common Factor of 490,355,514 is 1
Step 1: Since 490 > 355, we apply the division lemma to 490 and 355, to get
490 = 355 x 1 + 135
Step 2: Since the reminder 355 ≠ 0, we apply division lemma to 135 and 355, to get
355 = 135 x 2 + 85
Step 3: We consider the new divisor 135 and the new remainder 85, and apply the division lemma to get
135 = 85 x 1 + 50
We consider the new divisor 85 and the new remainder 50,and apply the division lemma to get
85 = 50 x 1 + 35
We consider the new divisor 50 and the new remainder 35,and apply the division lemma to get
50 = 35 x 1 + 15
We consider the new divisor 35 and the new remainder 15,and apply the division lemma to get
35 = 15 x 2 + 5
We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 490 and 355 is 5
Notice that 5 = HCF(15,5) = HCF(35,15) = HCF(50,35) = HCF(85,50) = HCF(135,85) = HCF(355,135) = HCF(490,355) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 514 > 5, we apply the division lemma to 514 and 5, to get
514 = 5 x 102 + 4
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get
5 = 4 x 1 + 1
Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 514 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(514,5) .
