HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 210, 145, 426 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 210, 145, 426 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 210, 145, 426 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 210, 145, 426 is 1.

HCF(210, 145, 426) = 1

HCF of 210, 145, 426 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 210, 145, 426 is 1.

Highest Common Factor of 210,145,426 using Euclid's algorithm

Highest Common Factor of 210,145,426 is 1

Step 1: Since 210 > 145, we apply the division lemma to 210 and 145, to get

210 = 145 x 1 + 65

Step 2: Since the reminder 145 ≠ 0, we apply division lemma to 65 and 145, to get

145 = 65 x 2 + 15

Step 3: We consider the new divisor 65 and the new remainder 15, and apply the division lemma to get

65 = 15 x 4 + 5

We consider the new divisor 15 and the new remainder 5, and apply the division lemma to get

15 = 5 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 210 and 145 is 5

Notice that 5 = HCF(15,5) = HCF(65,15) = HCF(145,65) = HCF(210,145) .


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

Step 1: Since 426 > 5, we apply the division lemma to 426 and 5, to get

426 = 5 x 85 + 1

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 426 is 1

Notice that 1 = HCF(5,1) = HCF(426,5) .
