HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 578, 943, 451 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 578, 943, 451 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 578, 943, 451 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 578, 943, 451 is 1.

HCF(578, 943, 451) = 1

HCF of 578, 943, 451 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 578, 943, 451 is 1.

Highest Common Factor of 578,943,451 using Euclid's algorithm

Highest Common Factor of 578,943,451 is 1

Step 1: Since 943 > 578, we apply the division lemma to 943 and 578, to get

943 = 578 x 1 + 365

Step 2: Since the reminder 578 ≠ 0, we apply division lemma to 365 and 578, to get

578 = 365 x 1 + 213

Step 3: We consider the new divisor 365 and the new remainder 213, and apply the division lemma to get

365 = 213 x 1 + 152

We consider the new divisor 213 and the new remainder 152,and apply the division lemma to get

213 = 152 x 1 + 61

We consider the new divisor 152 and the new remainder 61,and apply the division lemma to get

152 = 61 x 2 + 30

We consider the new divisor 61 and the new remainder 30,and apply the division lemma to get

61 = 30 x 2 + 1

We consider the new divisor 30 and the new remainder 1,and apply the division lemma to get

30 = 1 x 30 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 578 and 943 is 1

Notice that 1 = HCF(30,1) = HCF(61,30) = HCF(152,61) = HCF(213,152) = HCF(365,213) = HCF(578,365) = HCF(943,578) .

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

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

451 = 1 x 451 + 0

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

Notice that 1 = HCF(451,1) .
