HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 573, 309, 676 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 573, 309, 676 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 573, 309, 676 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 573, 309, 676 is 1.

HCF(573, 309, 676) = 1

Highest common factor (HCF) of 573, 309, 676 is 1.

Highest Common Factor of 573,309,676 using Euclid's algorithm

Highest Common Factor of 573,309,676 is 1

Step 1: Since 573 > 309, we apply the division lemma to 573 and 309, to get

573 = 309 x 1 + 264

Step 2: Since the reminder 309 ≠ 0, we apply division lemma to 264 and 309, to get

309 = 264 x 1 + 45

Step 3: We consider the new divisor 264 and the new remainder 45, and apply the division lemma to get

264 = 45 x 5 + 39

We consider the new divisor 45 and the new remainder 39,and apply the division lemma to get

45 = 39 x 1 + 6

We consider the new divisor 39 and the new remainder 6,and apply the division lemma to get

39 = 6 x 6 + 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 573 and 309 is 3

Notice that 3 = HCF(6,3) = HCF(39,6) = HCF(45,39) = HCF(264,45) = HCF(309,264) = HCF(573,309) .

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

Step 1: Since 676 > 3, we apply the division lemma to 676 and 3, to get

676 = 3 x 225 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 676 is 1

Notice that 1 = HCF(3,1) = HCF(676,3) .
