HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 635, 218, 348 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 635, 218, 348 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 635, 218, 348 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 635, 218, 348 is 1.

HCF(635, 218, 348) = 1

HCF of 635, 218, 348 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 635, 218, 348 is 1.

Highest Common Factor of 635,218,348 using Euclid's algorithm

Highest Common Factor of 635,218,348 is 1

Step 1: Since 635 > 218, we apply the division lemma to 635 and 218, to get

635 = 218 x 2 + 199

Step 2: Since the reminder 218 ≠ 0, we apply division lemma to 199 and 218, to get

218 = 199 x 1 + 19

Step 3: We consider the new divisor 199 and the new remainder 19, and apply the division lemma to get

199 = 19 x 10 + 9

We consider the new divisor 19 and the new remainder 9,and apply the division lemma to get

19 = 9 x 2 + 1

We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get

9 = 1 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 635 and 218 is 1

Notice that 1 = HCF(9,1) = HCF(19,9) = HCF(199,19) = HCF(218,199) = HCF(635,218) .

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

Step 1: Since 348 > 1, we apply the division lemma to 348 and 1, to get

348 = 1 x 348 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 348 is 1

Notice that 1 = HCF(348,1) .
