HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 410, 420, 23 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 410, 420, 23 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 410, 420, 23 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 410, 420, 23 is 1.

HCF(410, 420, 23) = 1

Highest common factor (HCF) of 410, 420, 23 is 1.

Highest Common Factor of 410,420,23 using Euclid's algorithm

Highest Common Factor of 410,420,23 is 1

Step 1: Since 420 > 410, we apply the division lemma to 420 and 410, to get

420 = 410 x 1 + 10

Step 2: Since the reminder 410 ≠ 0, we apply division lemma to 10 and 410, to get

410 = 10 x 41 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 410 and 420 is 10

Notice that 10 = HCF(410,10) = HCF(420,410) .


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

Step 1: Since 23 > 10, we apply the division lemma to 23 and 10, to get

23 = 10 x 2 + 3

Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 3 and 10, to get

10 = 3 x 3 + 1

Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 10 and 23 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(23,10) .
