HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 663, 838, 700 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 663, 838, 700 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 663, 838, 700 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 663, 838, 700 is 1.

HCF(663, 838, 700) = 1

HCF of 663, 838, 700 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 663, 838, 700 is 1.

Highest Common Factor of 663,838,700 using Euclid's algorithm

Highest Common Factor of 663,838,700 is 1

Step 1: Since 838 > 663, we apply the division lemma to 838 and 663, to get

838 = 663 x 1 + 175

Step 2: Since the reminder 663 ≠ 0, we apply division lemma to 175 and 663, to get

663 = 175 x 3 + 138

Step 3: We consider the new divisor 175 and the new remainder 138, and apply the division lemma to get

175 = 138 x 1 + 37

We consider the new divisor 138 and the new remainder 37,and apply the division lemma to get

138 = 37 x 3 + 27

We consider the new divisor 37 and the new remainder 27,and apply the division lemma to get

37 = 27 x 1 + 10

We consider the new divisor 27 and the new remainder 10,and apply the division lemma to get

27 = 10 x 2 + 7

We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get

10 = 7 x 1 + 3

We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get

7 = 3 x 2 + 1

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 663 and 838 is 1

Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(27,10) = HCF(37,27) = HCF(138,37) = HCF(175,138) = HCF(663,175) = HCF(838,663) .

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

Step 1: Since 700 > 1, we apply the division lemma to 700 and 1, to get

700 = 1 x 700 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 700 is 1

Notice that 1 = HCF(700,1) .
