HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 947, 520, 336 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 947, 520, 336 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, 520, 336 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, 520, 336 is 1.

HCF(947, 520, 336) = 1

Highest common factor (HCF) of 947, 520, 336 is 1.

Highest Common Factor of 947,520,336 using Euclid's algorithm

Highest Common Factor of 947,520,336 is 1

Step 1: Since 947 > 520, we apply the division lemma to 947 and 520, to get

947 = 520 x 1 + 427

Step 2: Since the reminder 520 ≠ 0, we apply division lemma to 427 and 520, to get

520 = 427 x 1 + 93

Step 3: We consider the new divisor 427 and the new remainder 93, and apply the division lemma to get

427 = 93 x 4 + 55

We consider the new divisor 93 and the new remainder 55,and apply the division lemma to get

93 = 55 x 1 + 38

We consider the new divisor 55 and the new remainder 38,and apply the division lemma to get

55 = 38 x 1 + 17

We consider the new divisor 38 and the new remainder 17,and apply the division lemma to get

38 = 17 x 2 + 4

We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get

17 = 4 x 4 + 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 520 is 1

Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(38,17) = HCF(55,38) = HCF(93,55) = HCF(427,93) = HCF(520,427) = HCF(947,520) .

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

Step 1: Since 336 > 1, we apply the division lemma to 336 and 1, to get

336 = 1 x 336 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 336 is 1

Notice that 1 = HCF(336,1) .
