HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 947, 618, 328 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 947, 618, 328 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 947, 618, 328 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 947, 618, 328 is 1.

HCF(947, 618, 328) = 1

Highest common factor (HCF) of 947, 618, 328 is 1.

Highest Common Factor of 947,618,328 using Euclid's algorithm

Highest Common Factor of 947,618,328 is 1

Step 1: Since 947 > 618, we apply the division lemma to 947 and 618, to get

947 = 618 x 1 + 329

Step 2: Since the reminder 618 ≠ 0, we apply division lemma to 329 and 618, to get

618 = 329 x 1 + 289

Step 3: We consider the new divisor 329 and the new remainder 289, and apply the division lemma to get

329 = 289 x 1 + 40

We consider the new divisor 289 and the new remainder 40,and apply the division lemma to get

289 = 40 x 7 + 9

We consider the new divisor 40 and the new remainder 9,and apply the division lemma to get

40 = 9 x 4 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 947 and 618 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(40,9) = HCF(289,40) = HCF(329,289) = HCF(618,329) = HCF(947,618) .

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

Step 1: Since 328 > 1, we apply the division lemma to 328 and 1, to get

328 = 1 x 328 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 328 is 1

Notice that 1 = HCF(328,1) .
