HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 945, 519 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 945, 519 is 3 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 945, 519 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 945, 519 is 3.

HCF(945, 519) = 3

Highest common factor (HCF) of 945, 519 is 3.

Highest Common Factor of 945,519 using Euclid's algorithm

Highest Common Factor of 945,519 is 3

Step 1: Since 945 > 519, we apply the division lemma to 945 and 519, to get

945 = 519 x 1 + 426

Step 2: Since the reminder 519 ≠ 0, we apply division lemma to 426 and 519, to get

519 = 426 x 1 + 93

Step 3: We consider the new divisor 426 and the new remainder 93, and apply the division lemma to get

426 = 93 x 4 + 54

We consider the new divisor 93 and the new remainder 54,and apply the division lemma to get

93 = 54 x 1 + 39

We consider the new divisor 54 and the new remainder 39,and apply the division lemma to get

54 = 39 x 1 + 15

We consider the new divisor 39 and the new remainder 15,and apply the division lemma to get

39 = 15 x 2 + 9

We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get

15 = 9 x 1 + 6

We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get

9 = 6 x 1 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 945 and 519 is 3

Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(39,15) = HCF(54,39) = HCF(93,54) = HCF(426,93) = HCF(519,426) = HCF(945,519) .
