HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 372, 936, 257 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 372, 936, 257 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 372, 936, 257 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 372, 936, 257 is 1.

HCF(372, 936, 257) = 1

HCF of 372, 936, 257 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 372, 936, 257 is 1.

Highest Common Factor of 372,936,257 using Euclid's algorithm

Highest Common Factor of 372,936,257 is 1

Step 1: Since 936 > 372, we apply the division lemma to 936 and 372, to get

936 = 372 x 2 + 192

Step 2: Since the reminder 372 ≠ 0, we apply division lemma to 192 and 372, to get

372 = 192 x 1 + 180

Step 3: We consider the new divisor 192 and the new remainder 180, and apply the division lemma to get

192 = 180 x 1 + 12

We consider the new divisor 180 and the new remainder 12, and apply the division lemma to get

180 = 12 x 15 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 372 and 936 is 12

Notice that 12 = HCF(180,12) = HCF(192,180) = HCF(372,192) = HCF(936,372) .

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

Step 1: Since 257 > 12, we apply the division lemma to 257 and 12, to get

257 = 12 x 21 + 5

Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 5 and 12, to get

12 = 5 x 2 + 2

Step 3: We consider the new divisor 5 and the new remainder 2, and apply the division lemma to get

5 = 2 x 2 + 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 12 and 257 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(257,12) .
