HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 451, 370, 74 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 451, 370, 74 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, 370, 74 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, 370, 74 is 1.

HCF(451, 370, 74) = 1

HCF of 451, 370, 74 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 451, 370, 74 is 1.

Highest Common Factor of 451,370,74 using Euclid's algorithm

Highest Common Factor of 451,370,74 is 1

Step 1: Since 451 > 370, we apply the division lemma to 451 and 370, to get

451 = 370 x 1 + 81

Step 2: Since the reminder 370 ≠ 0, we apply division lemma to 81 and 370, to get

370 = 81 x 4 + 46

Step 3: We consider the new divisor 81 and the new remainder 46, and apply the division lemma to get

81 = 46 x 1 + 35

We consider the new divisor 46 and the new remainder 35,and apply the division lemma to get

46 = 35 x 1 + 11

We consider the new divisor 35 and the new remainder 11,and apply the division lemma to get

35 = 11 x 3 + 2

We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get

11 = 2 x 5 + 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 451 and 370 is 1

Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(35,11) = HCF(46,35) = HCF(81,46) = HCF(370,81) = HCF(451,370) .

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

Step 1: Since 74 > 1, we apply the division lemma to 74 and 1, to get

74 = 1 x 74 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 74 is 1

Notice that 1 = HCF(74,1) .
