HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 603, 462, 969 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 603, 462, 969 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 603, 462, 969 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 603, 462, 969 is 3.

HCF(603, 462, 969) = 3

Highest common factor (HCF) of 603, 462, 969 is 3.

Highest Common Factor of 603,462,969 using Euclid's algorithm

Highest Common Factor of 603,462,969 is 3

Step 1: Since 603 > 462, we apply the division lemma to 603 and 462, to get

603 = 462 x 1 + 141

Step 2: Since the reminder 462 ≠ 0, we apply division lemma to 141 and 462, to get

462 = 141 x 3 + 39

Step 3: We consider the new divisor 141 and the new remainder 39, and apply the division lemma to get

141 = 39 x 3 + 24

We consider the new divisor 39 and the new remainder 24,and apply the division lemma to get

39 = 24 x 1 + 15

We consider the new divisor 24 and the new remainder 15,and apply the division lemma to get

24 = 15 x 1 + 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 603 and 462 is 3

Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(24,15) = HCF(39,24) = HCF(141,39) = HCF(462,141) = HCF(603,462) .

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

Step 1: Since 969 > 3, we apply the division lemma to 969 and 3, to get

969 = 3 x 323 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 969 is 3

Notice that 3 = HCF(969,3) .
