HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 827, 617, 121 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 827, 617, 121 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 827, 617, 121 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 827, 617, 121 is 1.

HCF(827, 617, 121) = 1

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

HCF of:

Highest common factor (HCF) of 827, 617, 121 is 1.

Highest Common Factor of 827,617,121 using Euclid's algorithm

Highest Common Factor of 827,617,121 is 1

Step 1: Since 827 > 617, we apply the division lemma to 827 and 617, to get

827 = 617 x 1 + 210

Step 2: Since the reminder 617 ≠ 0, we apply division lemma to 210 and 617, to get

617 = 210 x 2 + 197

Step 3: We consider the new divisor 210 and the new remainder 197, and apply the division lemma to get

210 = 197 x 1 + 13

We consider the new divisor 197 and the new remainder 13,and apply the division lemma to get

197 = 13 x 15 + 2

We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get

13 = 2 x 6 + 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 827 and 617 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(197,13) = HCF(210,197) = HCF(617,210) = HCF(827,617) .

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

Step 1: Since 121 > 1, we apply the division lemma to 121 and 1, to get

121 = 1 x 121 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 121 is 1

Notice that 1 = HCF(121,1) .
