HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 451, 353, 918 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 451, 353, 918 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 451, 353, 918 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 451, 353, 918 is 1.

HCF(451, 353, 918) = 1

Highest common factor (HCF) of 451, 353, 918 is 1.

Highest Common Factor of 451,353,918 using Euclid's algorithm

Highest Common Factor of 451,353,918 is 1

Step 1: Since 451 > 353, we apply the division lemma to 451 and 353, to get

451 = 353 x 1 + 98

Step 2: Since the reminder 353 ≠ 0, we apply division lemma to 98 and 353, to get

353 = 98 x 3 + 59

Step 3: We consider the new divisor 98 and the new remainder 59, and apply the division lemma to get

98 = 59 x 1 + 39

We consider the new divisor 59 and the new remainder 39,and apply the division lemma to get

59 = 39 x 1 + 20

We consider the new divisor 39 and the new remainder 20,and apply the division lemma to get

39 = 20 x 1 + 19

We consider the new divisor 20 and the new remainder 19,and apply the division lemma to get

20 = 19 x 1 + 1

We consider the new divisor 19 and the new remainder 1,and apply the division lemma to get

19 = 1 x 19 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 451 and 353 is 1

Notice that 1 = HCF(19,1) = HCF(20,19) = HCF(39,20) = HCF(59,39) = HCF(98,59) = HCF(353,98) = HCF(451,353) .

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

Step 1: Since 918 > 1, we apply the division lemma to 918 and 1, to get

918 = 1 x 918 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 918 is 1

Notice that 1 = HCF(918,1) .
