HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 508, 868, 705 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 508, 868, 705 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 508, 868, 705 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 508, 868, 705 is 1.

HCF(508, 868, 705) = 1

Highest Common Factor of 508,868,705 using Euclid's algorithm

Highest Common Factor of 508,868,705 is 1

Step 1: Since 868 > 508, we apply the division lemma to 868 and 508, to get

868 = 508 x 1 + 360

Step 2: Since the reminder 508 ≠ 0, we apply division lemma to 360 and 508, to get

508 = 360 x 1 + 148

Step 3: We consider the new divisor 360 and the new remainder 148, and apply the division lemma to get

360 = 148 x 2 + 64

We consider the new divisor 148 and the new remainder 64,and apply the division lemma to get

148 = 64 x 2 + 20

We consider the new divisor 64 and the new remainder 20,and apply the division lemma to get

64 = 20 x 3 + 4

We consider the new divisor 20 and the new remainder 4,and apply the division lemma to get

20 = 4 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 508 and 868 is 4

Notice that 4 = HCF(20,4) = HCF(64,20) = HCF(148,64) = HCF(360,148) = HCF(508,360) = HCF(868,508) .

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

Step 1: Since 705 > 4, we apply the division lemma to 705 and 4, to get

705 = 4 x 176 + 1

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, 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 4 and 705 is 1

Notice that 1 = HCF(4,1) = HCF(705,4) .
