HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 490, 710, 278 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 490, 710, 278 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, 710, 278 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, 710, 278 is 2.

HCF(490, 710, 278) = 2

Highest common factor (HCF) of 490, 710, 278 is 2.

Highest Common Factor of 490,710,278 using Euclid's algorithm

Highest Common Factor of 490,710,278 is 2

Step 1: Since 710 > 490, we apply the division lemma to 710 and 490, to get

710 = 490 x 1 + 220

Step 2: Since the reminder 490 ≠ 0, we apply division lemma to 220 and 490, to get

490 = 220 x 2 + 50

Step 3: We consider the new divisor 220 and the new remainder 50, and apply the division lemma to get

220 = 50 x 4 + 20

We consider the new divisor 50 and the new remainder 20,and apply the division lemma to get

50 = 20 x 2 + 10

We consider the new divisor 20 and the new remainder 10,and apply the division lemma to get

20 = 10 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 490 and 710 is 10

Notice that 10 = HCF(20,10) = HCF(50,20) = HCF(220,50) = HCF(490,220) = HCF(710,490) .


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

Step 1: Since 278 > 10, we apply the division lemma to 278 and 10, to get

278 = 10 x 27 + 8

Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 8 and 10, to get

10 = 8 x 1 + 2

Step 3: We consider the new divisor 8 and the new remainder 2, and apply the division lemma to get

8 = 2 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 10 and 278 is 2

Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(278,10) .
