HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 694, 315, 723 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 694, 315, 723 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 694, 315, 723 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 694, 315, 723 is 1.

HCF(694, 315, 723) = 1

Highest common factor (HCF) of 694, 315, 723 is 1.

Highest Common Factor of 694,315,723 using Euclid's algorithm

Highest Common Factor of 694,315,723 is 1

Step 1: Since 694 > 315, we apply the division lemma to 694 and 315, to get

694 = 315 x 2 + 64

Step 2: Since the reminder 315 ≠ 0, we apply division lemma to 64 and 315, to get

315 = 64 x 4 + 59

Step 3: We consider the new divisor 64 and the new remainder 59, and apply the division lemma to get

64 = 59 x 1 + 5

We consider the new divisor 59 and the new remainder 5,and apply the division lemma to get

59 = 5 x 11 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma 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 694 and 315 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(59,5) = HCF(64,59) = HCF(315,64) = HCF(694,315) .

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

Step 1: Since 723 > 1, we apply the division lemma to 723 and 1, to get

723 = 1 x 723 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 723 is 1

Notice that 1 = HCF(723,1) .
