HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 433, 238, 121 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 433, 238, 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, 238, 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, 238, 121 is 1.

HCF(433, 238, 121) = 1

Highest common factor (HCF) of 433, 238, 121 is 1.

Highest Common Factor of 433,238,121 using Euclid's algorithm

Highest Common Factor of 433,238,121 is 1

Step 1: Since 433 > 238, we apply the division lemma to 433 and 238, to get

433 = 238 x 1 + 195

Step 2: Since the reminder 238 ≠ 0, we apply division lemma to 195 and 238, to get

238 = 195 x 1 + 43

Step 3: We consider the new divisor 195 and the new remainder 43, and apply the division lemma to get

195 = 43 x 4 + 23

We consider the new divisor 43 and the new remainder 23,and apply the division lemma to get

43 = 23 x 1 + 20

We consider the new divisor 23 and the new remainder 20,and apply the division lemma to get

23 = 20 x 1 + 3

We consider the new divisor 20 and the new remainder 3,and apply the division lemma to get

20 = 3 x 6 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 433 and 238 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(20,3) = HCF(23,20) = HCF(43,23) = HCF(195,43) = HCF(238,195) = HCF(433,238) .

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) .
