HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 251, 855, 740, 45 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 251, 855, 740, 45 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 251, 855, 740, 45 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 251, 855, 740, 45 is 1.

HCF(251, 855, 740, 45) = 1

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

HCF of:

Highest common factor (HCF) of 251, 855, 740, 45 is 1.

Highest Common Factor of 251,855,740,45 using Euclid's algorithm

Highest Common Factor of 251,855,740,45 is 1

Step 1: Since 855 > 251, we apply the division lemma to 855 and 251, to get

855 = 251 x 3 + 102

Step 2: Since the reminder 251 ≠ 0, we apply division lemma to 102 and 251, to get

251 = 102 x 2 + 47

Step 3: We consider the new divisor 102 and the new remainder 47, and apply the division lemma to get

102 = 47 x 2 + 8

We consider the new divisor 47 and the new remainder 8,and apply the division lemma to get

47 = 8 x 5 + 7

We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get

8 = 7 x 1 + 1

We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 251 and 855 is 1

Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(47,8) = HCF(102,47) = HCF(251,102) = HCF(855,251) .


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

Step 1: Since 740 > 1, we apply the division lemma to 740 and 1, to get

740 = 1 x 740 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 740 is 1

Notice that 1 = HCF(740,1) .


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

Step 1: Since 45 > 1, we apply the division lemma to 45 and 1, to get

45 = 1 x 45 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 45 is 1

Notice that 1 = HCF(45,1) .
