HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 987, 937, 245 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 987, 937, 245 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, 937, 245 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, 937, 245 is 1.

HCF(987, 937, 245) = 1

HCF of 987, 937, 245 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 987, 937, 245 is 1.

Highest Common Factor of 987,937,245 using Euclid's algorithm

Highest Common Factor of 987,937,245 is 1

Step 1: Since 987 > 937, we apply the division lemma to 987 and 937, to get

987 = 937 x 1 + 50

Step 2: Since the reminder 937 ≠ 0, we apply division lemma to 50 and 937, to get

937 = 50 x 18 + 37

Step 3: We consider the new divisor 50 and the new remainder 37, and apply the division lemma to get

50 = 37 x 1 + 13

We consider the new divisor 37 and the new remainder 13,and apply the division lemma to get

37 = 13 x 2 + 11

We consider the new divisor 13 and the new remainder 11,and apply the division lemma to get

13 = 11 x 1 + 2

We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get

11 = 2 x 5 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 987 and 937 is 1

Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(37,13) = HCF(50,37) = HCF(937,50) = HCF(987,937) .

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

Step 1: Since 245 > 1, we apply the division lemma to 245 and 1, to get

245 = 1 x 245 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 245 is 1

Notice that 1 = HCF(245,1) .
