HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 673, 489, 591, 287 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 673, 489, 591, 287 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 673, 489, 591, 287 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 673, 489, 591, 287 is 1.

HCF(673, 489, 591, 287) = 1

Highest common factor (HCF) of 673, 489, 591, 287 is 1.

Highest Common Factor of 673,489,591,287 using Euclid's algorithm

Highest Common Factor of 673,489,591,287 is 1

Step 1: Since 673 > 489, we apply the division lemma to 673 and 489, to get

673 = 489 x 1 + 184

Step 2: Since the reminder 489 ≠ 0, we apply division lemma to 184 and 489, to get

489 = 184 x 2 + 121

Step 3: We consider the new divisor 184 and the new remainder 121, and apply the division lemma to get

184 = 121 x 1 + 63

We consider the new divisor 121 and the new remainder 63,and apply the division lemma to get

121 = 63 x 1 + 58

We consider the new divisor 63 and the new remainder 58,and apply the division lemma to get

63 = 58 x 1 + 5

We consider the new divisor 58 and the new remainder 5,and apply the division lemma to get

58 = 5 x 11 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 673 and 489 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(58,5) = HCF(63,58) = HCF(121,63) = HCF(184,121) = HCF(489,184) = HCF(673,489) .

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

Step 1: Since 591 > 1, we apply the division lemma to 591 and 1, to get

591 = 1 x 591 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 591 is 1

Notice that 1 = HCF(591,1) .

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

Step 1: Since 287 > 1, we apply the division lemma to 287 and 1, to get

287 = 1 x 287 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 287 is 1

Notice that 1 = HCF(287,1) .
