HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 284, 791, 206, 80 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 284, 791, 206, 80 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 284, 791, 206, 80 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 284, 791, 206, 80 is 1.

HCF(284, 791, 206, 80) = 1

Highest Common Factor of 284,791,206,80 using Euclid's algorithm

Highest Common Factor of 284,791,206,80 is 1

Step 1: Since 791 > 284, we apply the division lemma to 791 and 284, to get

791 = 284 x 2 + 223

Step 2: Since the reminder 284 ≠ 0, we apply division lemma to 223 and 284, to get

284 = 223 x 1 + 61

Step 3: We consider the new divisor 223 and the new remainder 61, and apply the division lemma to get

223 = 61 x 3 + 40

We consider the new divisor 61 and the new remainder 40,and apply the division lemma to get

61 = 40 x 1 + 21

We consider the new divisor 40 and the new remainder 21,and apply the division lemma to get

40 = 21 x 1 + 19

We consider the new divisor 21 and the new remainder 19,and apply the division lemma to get

21 = 19 x 1 + 2

We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get

19 = 2 x 9 + 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 284 and 791 is 1

Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(21,19) = HCF(40,21) = HCF(61,40) = HCF(223,61) = HCF(284,223) = HCF(791,284) .

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

Step 1: Since 206 > 1, we apply the division lemma to 206 and 1, to get

206 = 1 x 206 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 206 is 1

Notice that 1 = HCF(206,1) .

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

Step 1: Since 80 > 1, we apply the division lemma to 80 and 1, to get

80 = 1 x 80 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 80 is 1

Notice that 1 = HCF(80,1) .
