HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 913, 673, 489 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 913, 673, 489 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 913, 673, 489 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 913, 673, 489 is 1.

HCF(913, 673, 489) = 1

Highest common factor (HCF) of 913, 673, 489 is 1.

Highest Common Factor of 913,673,489 using Euclid's algorithm

Highest Common Factor of 913,673,489 is 1

Step 1: Since 913 > 673, we apply the division lemma to 913 and 673, to get

913 = 673 x 1 + 240

Step 2: Since the reminder 673 ≠ 0, we apply division lemma to 240 and 673, to get

673 = 240 x 2 + 193

Step 3: We consider the new divisor 240 and the new remainder 193, and apply the division lemma to get

240 = 193 x 1 + 47

We consider the new divisor 193 and the new remainder 47,and apply the division lemma to get

193 = 47 x 4 + 5

We consider the new divisor 47 and the new remainder 5,and apply the division lemma to get

47 = 5 x 9 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 913 and 673 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(47,5) = HCF(193,47) = HCF(240,193) = HCF(673,240) = HCF(913,673) .

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

Step 1: Since 489 > 1, we apply the division lemma to 489 and 1, to get

489 = 1 x 489 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 489 is 1

Notice that 1 = HCF(489,1) .
