HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 473, 257, 658, 80 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 473, 257, 658, 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 473, 257, 658, 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 473, 257, 658, 80 is 1.

HCF(473, 257, 658, 80) = 1

Highest Common Factor of 473,257,658,80 using Euclid's algorithm

Highest Common Factor of 473,257,658,80 is 1

Step 1: Since 473 > 257, we apply the division lemma to 473 and 257, to get

473 = 257 x 1 + 216

Step 2: Since the reminder 257 ≠ 0, we apply division lemma to 216 and 257, to get

257 = 216 x 1 + 41

Step 3: We consider the new divisor 216 and the new remainder 41, and apply the division lemma to get

216 = 41 x 5 + 11

We consider the new divisor 41 and the new remainder 11,and apply the division lemma to get

41 = 11 x 3 + 8

We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get

11 = 8 x 1 + 3

We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get

8 = 3 x 2 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 473 and 257 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(41,11) = HCF(216,41) = HCF(257,216) = HCF(473,257) .

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

Step 1: Since 658 > 1, we apply the division lemma to 658 and 1, to get

658 = 1 x 658 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 658 is 1

Notice that 1 = HCF(658,1) .

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) .
