HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 163, 450, 649 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 163, 450, 649 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 163, 450, 649 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 163, 450, 649 is 1.

HCF(163, 450, 649) = 1

HCF of 163, 450, 649 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 163, 450, 649 is 1.

Highest Common Factor of 163,450,649 using Euclid's algorithm

Highest Common Factor of 163,450,649 is 1

Step 1: Since 450 > 163, we apply the division lemma to 450 and 163, to get

450 = 163 x 2 + 124

Step 2: Since the reminder 163 ≠ 0, we apply division lemma to 124 and 163, to get

163 = 124 x 1 + 39

Step 3: We consider the new divisor 124 and the new remainder 39, and apply the division lemma to get

124 = 39 x 3 + 7

We consider the new divisor 39 and the new remainder 7,and apply the division lemma to get

39 = 7 x 5 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 163 and 450 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(39,7) = HCF(124,39) = HCF(163,124) = HCF(450,163) .

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

Step 1: Since 649 > 1, we apply the division lemma to 649 and 1, to get

649 = 1 x 649 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 649 is 1

Notice that 1 = HCF(649,1) .
