HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 513, 288, 971, 27 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 513, 288, 971, 27 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 513, 288, 971, 27 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 513, 288, 971, 27 is 1.

HCF(513, 288, 971, 27) = 1

Highest Common Factor of 513,288,971,27 using Euclid's algorithm

Highest Common Factor of 513,288,971,27 is 1

Step 1: Since 513 > 288, we apply the division lemma to 513 and 288, to get

513 = 288 x 1 + 225

Step 2: Since the reminder 288 ≠ 0, we apply division lemma to 225 and 288, to get

288 = 225 x 1 + 63

Step 3: We consider the new divisor 225 and the new remainder 63, and apply the division lemma to get

225 = 63 x 3 + 36

We consider the new divisor 63 and the new remainder 36,and apply the division lemma to get

63 = 36 x 1 + 27

We consider the new divisor 36 and the new remainder 27,and apply the division lemma to get

36 = 27 x 1 + 9

We consider the new divisor 27 and the new remainder 9,and apply the division lemma to get

27 = 9 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 513 and 288 is 9

Notice that 9 = HCF(27,9) = HCF(36,27) = HCF(63,36) = HCF(225,63) = HCF(288,225) = HCF(513,288) .

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

Step 1: Since 971 > 9, we apply the division lemma to 971 and 9, to get

971 = 9 x 107 + 8

Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 8 and 9, to get

9 = 8 x 1 + 1

Step 3: We consider the new divisor 8 and the new remainder 1, and apply the division lemma to get

8 = 1 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 9 and 971 is 1

Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(971,9) .

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

Step 1: Since 27 > 1, we apply the division lemma to 27 and 1, to get

27 = 1 x 27 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 27 is 1

Notice that 1 = HCF(27,1) .
