HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 324, 551, 257 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 324, 551, 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 324, 551, 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 324, 551, 257 is 1.

HCF(324, 551, 257) = 1

HCF of 324, 551, 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 324, 551, 257 is 1.

Highest Common Factor of 324,551,257 using Euclid's algorithm

Highest Common Factor of 324,551,257 is 1

Step 1: Since 551 > 324, we apply the division lemma to 551 and 324, to get

551 = 324 x 1 + 227

Step 2: Since the reminder 324 ≠ 0, we apply division lemma to 227 and 324, to get

324 = 227 x 1 + 97

Step 3: We consider the new divisor 227 and the new remainder 97, and apply the division lemma to get

227 = 97 x 2 + 33

We consider the new divisor 97 and the new remainder 33,and apply the division lemma to get

97 = 33 x 2 + 31

We consider the new divisor 33 and the new remainder 31,and apply the division lemma to get

33 = 31 x 1 + 2

We consider the new divisor 31 and the new remainder 2,and apply the division lemma to get

31 = 2 x 15 + 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 324 and 551 is 1

Notice that 1 = HCF(2,1) = HCF(31,2) = HCF(33,31) = HCF(97,33) = HCF(227,97) = HCF(324,227) = HCF(551,324) .

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

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

257 = 1 x 257 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 257 is 1

Notice that 1 = HCF(257,1) .
