HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 359, 919, 991 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 359, 919, 991 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 359, 919, 991 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 359, 919, 991 is 1.

HCF(359, 919, 991) = 1

HCF of 359, 919, 991 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 359, 919, 991 is 1.

Highest Common Factor of 359,919,991 using Euclid's algorithm

Highest Common Factor of 359,919,991 is 1

Step 1: Since 919 > 359, we apply the division lemma to 919 and 359, to get

919 = 359 x 2 + 201

Step 2: Since the reminder 359 ≠ 0, we apply division lemma to 201 and 359, to get

359 = 201 x 1 + 158

Step 3: We consider the new divisor 201 and the new remainder 158, and apply the division lemma to get

201 = 158 x 1 + 43

We consider the new divisor 158 and the new remainder 43,and apply the division lemma to get

158 = 43 x 3 + 29

We consider the new divisor 43 and the new remainder 29,and apply the division lemma to get

43 = 29 x 1 + 14

We consider the new divisor 29 and the new remainder 14,and apply the division lemma to get

29 = 14 x 2 + 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 359 and 919 is 1

Notice that 1 = HCF(14,1) = HCF(29,14) = HCF(43,29) = HCF(158,43) = HCF(201,158) = HCF(359,201) = HCF(919,359) .

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

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

991 = 1 x 991 + 0

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

Notice that 1 = HCF(991,1) .
