HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 987, 362, 813, 44 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 987, 362, 813, 44 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 987, 362, 813, 44 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 987, 362, 813, 44 is 1.

HCF(987, 362, 813, 44) = 1

Highest common factor (HCF) of 987, 362, 813, 44 is 1.

Highest Common Factor of 987,362,813,44 using Euclid's algorithm

Highest Common Factor of 987,362,813,44 is 1

Step 1: Since 987 > 362, we apply the division lemma to 987 and 362, to get

987 = 362 x 2 + 263

Step 2: Since the reminder 362 ≠ 0, we apply division lemma to 263 and 362, to get

362 = 263 x 1 + 99

Step 3: We consider the new divisor 263 and the new remainder 99, and apply the division lemma to get

263 = 99 x 2 + 65

We consider the new divisor 99 and the new remainder 65,and apply the division lemma to get

99 = 65 x 1 + 34

We consider the new divisor 65 and the new remainder 34,and apply the division lemma to get

65 = 34 x 1 + 31

We consider the new divisor 34 and the new remainder 31,and apply the division lemma to get

34 = 31 x 1 + 3

We consider the new divisor 31 and the new remainder 3,and apply the division lemma to get

31 = 3 x 10 + 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 987 and 362 is 1

Notice that 1 = HCF(3,1) = HCF(31,3) = HCF(34,31) = HCF(65,34) = HCF(99,65) = HCF(263,99) = HCF(362,263) = HCF(987,362) .

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

Step 1: Since 813 > 1, we apply the division lemma to 813 and 1, to get

813 = 1 x 813 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 813 is 1

Notice that 1 = HCF(813,1) .

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

Step 1: Since 44 > 1, we apply the division lemma to 44 and 1, to get

44 = 1 x 44 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 44 is 1

Notice that 1 = HCF(44,1) .
