HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 830, 490, 265 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 830, 490, 265 is 5 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 830, 490, 265 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 830, 490, 265 is 5.

HCF(830, 490, 265) = 5

Highest Common Factor of 830,490,265 using Euclid's algorithm

Highest Common Factor of 830,490,265 is 5

Step 1: Since 830 > 490, we apply the division lemma to 830 and 490, to get

830 = 490 x 1 + 340

Step 2: Since the reminder 490 ≠ 0, we apply division lemma to 340 and 490, to get

490 = 340 x 1 + 150

Step 3: We consider the new divisor 340 and the new remainder 150, and apply the division lemma to get

340 = 150 x 2 + 40

We consider the new divisor 150 and the new remainder 40,and apply the division lemma to get

150 = 40 x 3 + 30

We consider the new divisor 40 and the new remainder 30,and apply the division lemma to get

40 = 30 x 1 + 10

We consider the new divisor 30 and the new remainder 10,and apply the division lemma to get

30 = 10 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 830 and 490 is 10

Notice that 10 = HCF(30,10) = HCF(40,30) = HCF(150,40) = HCF(340,150) = HCF(490,340) = HCF(830,490) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 265 > 10, we apply the division lemma to 265 and 10, to get

265 = 10 x 26 + 5

Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 5 and 10, 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 10 and 265 is 5

Notice that 5 = HCF(10,5) = HCF(265,10) .
