HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 751, 921, 499 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 751, 921, 499 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 751, 921, 499 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 751, 921, 499 is 1.

HCF(751, 921, 499) = 1

Highest common factor (HCF) of 751, 921, 499 is 1.

Highest Common Factor of 751,921,499 using Euclid's algorithm

Highest Common Factor of 751,921,499 is 1

Step 1: Since 921 > 751, we apply the division lemma to 921 and 751, to get

921 = 751 x 1 + 170

Step 2: Since the reminder 751 ≠ 0, we apply division lemma to 170 and 751, to get

751 = 170 x 4 + 71

Step 3: We consider the new divisor 170 and the new remainder 71, and apply the division lemma to get

170 = 71 x 2 + 28

We consider the new divisor 71 and the new remainder 28,and apply the division lemma to get

71 = 28 x 2 + 15

We consider the new divisor 28 and the new remainder 15,and apply the division lemma to get

28 = 15 x 1 + 13

We consider the new divisor 15 and the new remainder 13,and apply the division lemma to get

15 = 13 x 1 + 2

We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get

13 = 2 x 6 + 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 751 and 921 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(28,15) = HCF(71,28) = HCF(170,71) = HCF(751,170) = HCF(921,751) .


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

Step 1: Since 499 > 1, we apply the division lemma to 499 and 1, to get

499 = 1 x 499 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 499 is 1

Notice that 1 = HCF(499,1) .
