HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 718, 606, 820, 251 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 718, 606, 820, 251 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 718, 606, 820, 251 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 718, 606, 820, 251 is 1.

HCF(718, 606, 820, 251) = 1

Highest Common Factor of 718,606,820,251 using Euclid's algorithm

Highest Common Factor of 718,606,820,251 is 1

Step 1: Since 718 > 606, we apply the division lemma to 718 and 606, to get

718 = 606 x 1 + 112

Step 2: Since the reminder 606 ≠ 0, we apply division lemma to 112 and 606, to get

606 = 112 x 5 + 46

Step 3: We consider the new divisor 112 and the new remainder 46, and apply the division lemma to get

112 = 46 x 2 + 20

We consider the new divisor 46 and the new remainder 20,and apply the division lemma to get

46 = 20 x 2 + 6

We consider the new divisor 20 and the new remainder 6,and apply the division lemma to get

20 = 6 x 3 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 718 and 606 is 2

Notice that 2 = HCF(6,2) = HCF(20,6) = HCF(46,20) = HCF(112,46) = HCF(606,112) = HCF(718,606) .

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

Step 1: Since 820 > 2, we apply the division lemma to 820 and 2, to get

820 = 2 x 410 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 820 is 2

Notice that 2 = HCF(820,2) .

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

Step 1: Since 251 > 2, we apply the division lemma to 251 and 2, to get

251 = 2 x 125 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 251 is 1

Notice that 1 = HCF(2,1) = HCF(251,2) .
