HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 553, 312, 109, 51 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 553, 312, 109, 51 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 553, 312, 109, 51 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 553, 312, 109, 51 is 1.

HCF(553, 312, 109, 51) = 1

Highest Common Factor of 553,312,109,51 using Euclid's algorithm

Highest Common Factor of 553,312,109,51 is 1

Step 1: Since 553 > 312, we apply the division lemma to 553 and 312, to get

553 = 312 x 1 + 241

Step 2: Since the reminder 312 ≠ 0, we apply division lemma to 241 and 312, to get

312 = 241 x 1 + 71

Step 3: We consider the new divisor 241 and the new remainder 71, and apply the division lemma to get

241 = 71 x 3 + 28

We consider the new divisor 71 and the new remainder 28,and apply the division lemma to get

71 = 28 x 2 + 15

We consider the new divisor 28 and the new remainder 15,and apply the division lemma to get

28 = 15 x 1 + 13

We consider the new divisor 15 and the new remainder 13,and apply the division lemma to get

15 = 13 x 1 + 2

We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get

13 = 2 x 6 + 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 553 and 312 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(28,15) = HCF(71,28) = HCF(241,71) = HCF(312,241) = HCF(553,312) .

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

Step 1: Since 109 > 1, we apply the division lemma to 109 and 1, to get

109 = 1 x 109 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 109 is 1

Notice that 1 = HCF(109,1) .

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

Step 1: Since 51 > 1, we apply the division lemma to 51 and 1, to get

51 = 1 x 51 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 51 is 1

Notice that 1 = HCF(51,1) .
