HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 909, 513, 673, 748 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 909, 513, 673, 748 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 909, 513, 673, 748 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 909, 513, 673, 748 is 1.

HCF(909, 513, 673, 748) = 1

Highest common factor (HCF) of 909, 513, 673, 748 is 1.

Highest Common Factor of 909,513,673,748 using Euclid's algorithm

Highest Common Factor of 909,513,673,748 is 1

Step 1: Since 909 > 513, we apply the division lemma to 909 and 513, to get

909 = 513 x 1 + 396

Step 2: Since the reminder 513 ≠ 0, we apply division lemma to 396 and 513, to get

513 = 396 x 1 + 117

Step 3: We consider the new divisor 396 and the new remainder 117, and apply the division lemma to get

396 = 117 x 3 + 45

We consider the new divisor 117 and the new remainder 45,and apply the division lemma to get

117 = 45 x 2 + 27

We consider the new divisor 45 and the new remainder 27,and apply the division lemma to get

45 = 27 x 1 + 18

We consider the new divisor 27 and the new remainder 18,and apply the division lemma to get

27 = 18 x 1 + 9

We consider the new divisor 18 and the new remainder 9,and apply the division lemma to get

18 = 9 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 909 and 513 is 9

Notice that 9 = HCF(18,9) = HCF(27,18) = HCF(45,27) = HCF(117,45) = HCF(396,117) = HCF(513,396) = HCF(909,513) .

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

Step 1: Since 673 > 9, we apply the division lemma to 673 and 9, to get

673 = 9 x 74 + 7

Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 7 and 9, to get

9 = 7 x 1 + 2

Step 3: We consider the new divisor 7 and the new remainder 2, and apply the division lemma to get

7 = 2 x 3 + 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 9 and 673 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(673,9) .

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

Step 1: Since 748 > 1, we apply the division lemma to 748 and 1, to get

748 = 1 x 748 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 748 is 1

Notice that 1 = HCF(748,1) .
