HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 648, 990, 295, 41 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 648, 990, 295, 41 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 648, 990, 295, 41 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 648, 990, 295, 41 is 1.

HCF(648, 990, 295, 41) = 1

Highest common factor (HCF) of 648, 990, 295, 41 is 1.

Highest Common Factor of 648,990,295,41 using Euclid's algorithm

Highest Common Factor of 648,990,295,41 is 1

Step 1: Since 990 > 648, we apply the division lemma to 990 and 648, to get

990 = 648 x 1 + 342

Step 2: Since the reminder 648 ≠ 0, we apply division lemma to 342 and 648, to get

648 = 342 x 1 + 306

Step 3: We consider the new divisor 342 and the new remainder 306, and apply the division lemma to get

342 = 306 x 1 + 36

We consider the new divisor 306 and the new remainder 36,and apply the division lemma to get

306 = 36 x 8 + 18

We consider the new divisor 36 and the new remainder 18,and apply the division lemma to get

36 = 18 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 648 and 990 is 18

Notice that 18 = HCF(36,18) = HCF(306,36) = HCF(342,306) = HCF(648,342) = HCF(990,648) .

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

Step 1: Since 295 > 18, we apply the division lemma to 295 and 18, to get

295 = 18 x 16 + 7

Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 7 and 18, to get

18 = 7 x 2 + 4

Step 3: 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 18 and 295 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(18,7) = HCF(295,18) .

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

Step 1: Since 41 > 1, we apply the division lemma to 41 and 1, to get

41 = 1 x 41 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 41 is 1

Notice that 1 = HCF(41,1) .
