HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 490, 365, 306 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 490, 365, 306 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, 365, 306 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, 365, 306 is 1.
HCF(490, 365, 306) = 1
HCF of 490, 365, 306 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, 365, 306 is 1.
Highest Common Factor of 490,365,306 is 1
Step 1: Since 490 > 365, we apply the division lemma to 490 and 365, to get
490 = 365 x 1 + 125
Step 2: Since the reminder 365 ≠ 0, we apply division lemma to 125 and 365, to get
365 = 125 x 2 + 115
Step 3: We consider the new divisor 125 and the new remainder 115, and apply the division lemma to get
125 = 115 x 1 + 10
We consider the new divisor 115 and the new remainder 10,and apply the division lemma to get
115 = 10 x 11 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 490 and 365 is 5
Notice that 5 = HCF(10,5) = HCF(115,10) = HCF(125,115) = HCF(365,125) = HCF(490,365) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 306 > 5, we apply the division lemma to 306 and 5, to get
306 = 5 x 61 + 1
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 306 is 1
Notice that 1 = HCF(5,1) = HCF(306,5) .
