HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 400, 473, 689 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 400, 473, 689 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 400, 473, 689 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 400, 473, 689 is 1.

HCF(400, 473, 689) = 1

Highest common factor (HCF) of 400, 473, 689 is 1.

Highest Common Factor of 400,473,689 using Euclid's algorithm

Highest Common Factor of 400,473,689 is 1

Step 1: Since 473 > 400, we apply the division lemma to 473 and 400, to get

473 = 400 x 1 + 73

Step 2: Since the reminder 400 ≠ 0, we apply division lemma to 73 and 400, to get

400 = 73 x 5 + 35

Step 3: We consider the new divisor 73 and the new remainder 35, and apply the division lemma to get

73 = 35 x 2 + 3

We consider the new divisor 35 and the new remainder 3,and apply the division lemma to get

35 = 3 x 11 + 2

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

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 400 and 473 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(35,3) = HCF(73,35) = HCF(400,73) = HCF(473,400) .

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

Step 1: Since 689 > 1, we apply the division lemma to 689 and 1, to get

689 = 1 x 689 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 689 is 1

Notice that 1 = HCF(689,1) .
