HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 433, 664, 121 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 433, 664, 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 433, 664, 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 433, 664, 121 is 1.

HCF(433, 664, 121) = 1

HCF of 433, 664, 121 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 433, 664, 121 is 1.

Highest Common Factor of 433,664,121 using Euclid's algorithm

Highest Common Factor of 433,664,121 is 1

Step 1: Since 664 > 433, we apply the division lemma to 664 and 433, to get

664 = 433 x 1 + 231

Step 2: Since the reminder 433 ≠ 0, we apply division lemma to 231 and 433, to get

433 = 231 x 1 + 202

Step 3: We consider the new divisor 231 and the new remainder 202, and apply the division lemma to get

231 = 202 x 1 + 29

We consider the new divisor 202 and the new remainder 29,and apply the division lemma to get

202 = 29 x 6 + 28

We consider the new divisor 29 and the new remainder 28,and apply the division lemma to get

29 = 28 x 1 + 1

We consider the new divisor 28 and the new remainder 1,and apply the division lemma to get

28 = 1 x 28 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 433 and 664 is 1

Notice that 1 = HCF(28,1) = HCF(29,28) = HCF(202,29) = HCF(231,202) = HCF(433,231) = HCF(664,433) .

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) .
