HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 991, 2337, 1950 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 991, 2337, 1950 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 991, 2337, 1950 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 991, 2337, 1950 is 1.

HCF(991, 2337, 1950) = 1

HCF of 991, 2337, 1950 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 991, 2337, 1950 is 1.

Highest Common Factor of 991,2337,1950 using Euclid's algorithm

Highest Common Factor of 991,2337,1950 is 1

Step 1: Since 2337 > 991, we apply the division lemma to 2337 and 991, to get

2337 = 991 x 2 + 355

Step 2: Since the reminder 991 ≠ 0, we apply division lemma to 355 and 991, to get

991 = 355 x 2 + 281

Step 3: We consider the new divisor 355 and the new remainder 281, and apply the division lemma to get

355 = 281 x 1 + 74

We consider the new divisor 281 and the new remainder 74,and apply the division lemma to get

281 = 74 x 3 + 59

We consider the new divisor 74 and the new remainder 59,and apply the division lemma to get

74 = 59 x 1 + 15

We consider the new divisor 59 and the new remainder 15,and apply the division lemma to get

59 = 15 x 3 + 14

We consider the new divisor 15 and the new remainder 14,and apply the division lemma to get

15 = 14 x 1 + 1

We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get

14 = 1 x 14 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 991 and 2337 is 1

Notice that 1 = HCF(14,1) = HCF(15,14) = HCF(59,15) = HCF(74,59) = HCF(281,74) = HCF(355,281) = HCF(991,355) = HCF(2337,991) .

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

Step 1: Since 1950 > 1, we apply the division lemma to 1950 and 1, to get

1950 = 1 x 1950 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 1950 is 1

Notice that 1 = HCF(1950,1) .
