HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 947, 245, 580 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 947, 245, 580 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, 245, 580 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, 245, 580 is 1.

HCF(947, 245, 580) = 1

Highest common factor (HCF) of 947, 245, 580 is 1.

Highest Common Factor of 947,245,580 using Euclid's algorithm

Highest Common Factor of 947,245,580 is 1

Step 1: Since 947 > 245, we apply the division lemma to 947 and 245, to get

947 = 245 x 3 + 212

Step 2: Since the reminder 245 ≠ 0, we apply division lemma to 212 and 245, to get

245 = 212 x 1 + 33

Step 3: We consider the new divisor 212 and the new remainder 33, and apply the division lemma to get

212 = 33 x 6 + 14

We consider the new divisor 33 and the new remainder 14,and apply the division lemma to get

33 = 14 x 2 + 5

We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get

14 = 5 x 2 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 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 245 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(33,14) = HCF(212,33) = HCF(245,212) = HCF(947,245) .

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

Step 1: Since 580 > 1, we apply the division lemma to 580 and 1, to get

580 = 1 x 580 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 580 is 1

Notice that 1 = HCF(580,1) .
