HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 490, 740, 396, 300 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 490, 740, 396, 300 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 490, 740, 396, 300 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, 740, 396, 300 is 2.
HCF(490, 740, 396, 300) = 2
HCF of 490, 740, 396, 300 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, 740, 396, 300 is 2.
Highest Common Factor of 490,740,396,300 is 2
Step 1: Since 740 > 490, we apply the division lemma to 740 and 490, to get
740 = 490 x 1 + 250
Step 2: Since the reminder 490 ≠ 0, we apply division lemma to 250 and 490, to get
490 = 250 x 1 + 240
Step 3: We consider the new divisor 250 and the new remainder 240, and apply the division lemma to get
250 = 240 x 1 + 10
We consider the new divisor 240 and the new remainder 10, and apply the division lemma to get
240 = 10 x 24 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 490 and 740 is 10
Notice that 10 = HCF(240,10) = HCF(250,240) = HCF(490,250) = HCF(740,490) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 396 > 10, we apply the division lemma to 396 and 10, to get
396 = 10 x 39 + 6
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 6 and 10, to get
10 = 6 x 1 + 4
Step 3: We consider the new divisor 6 and the new remainder 4, and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 10 and 396 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(396,10) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 300 > 2, we apply the division lemma to 300 and 2, to get
300 = 2 x 150 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 300 is 2
Notice that 2 = HCF(300,2) .
