HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 513, 789, 437 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 513, 789, 437 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, 789, 437 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, 789, 437 is 1.

HCF(513, 789, 437) = 1

Highest common factor (HCF) of 513, 789, 437 is 1.

Highest Common Factor of 513,789,437 using Euclid's algorithm

Highest Common Factor of 513,789,437 is 1

Step 1: Since 789 > 513, we apply the division lemma to 789 and 513, to get

789 = 513 x 1 + 276

Step 2: Since the reminder 513 ≠ 0, we apply division lemma to 276 and 513, to get

513 = 276 x 1 + 237

Step 3: We consider the new divisor 276 and the new remainder 237, and apply the division lemma to get

276 = 237 x 1 + 39

We consider the new divisor 237 and the new remainder 39,and apply the division lemma to get

237 = 39 x 6 + 3

We consider the new divisor 39 and the new remainder 3,and apply the division lemma to get

39 = 3 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 513 and 789 is 3

Notice that 3 = HCF(39,3) = HCF(237,39) = HCF(276,237) = HCF(513,276) = HCF(789,513) .

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

Step 1: Since 437 > 3, we apply the division lemma to 437 and 3, to get

437 = 3 x 145 + 2

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get

3 = 2 x 1 + 1

Step 3: 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 3 and 437 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(437,3) .
