HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 782, 573, 302 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 782, 573, 302 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 782, 573, 302 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 782, 573, 302 is 1.

HCF(782, 573, 302) = 1

Highest common factor (HCF) of 782, 573, 302 is 1.

Highest Common Factor of 782,573,302 using Euclid's algorithm

Highest Common Factor of 782,573,302 is 1

Step 1: Since 782 > 573, we apply the division lemma to 782 and 573, to get

782 = 573 x 1 + 209

Step 2: Since the reminder 573 ≠ 0, we apply division lemma to 209 and 573, to get

573 = 209 x 2 + 155

Step 3: We consider the new divisor 209 and the new remainder 155, and apply the division lemma to get

209 = 155 x 1 + 54

We consider the new divisor 155 and the new remainder 54,and apply the division lemma to get

155 = 54 x 2 + 47

We consider the new divisor 54 and the new remainder 47,and apply the division lemma to get

54 = 47 x 1 + 7

We consider the new divisor 47 and the new remainder 7,and apply the division lemma to get

47 = 7 x 6 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 782 and 573 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(47,7) = HCF(54,47) = HCF(155,54) = HCF(209,155) = HCF(573,209) = HCF(782,573) .

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

Step 1: Since 302 > 1, we apply the division lemma to 302 and 1, to get

302 = 1 x 302 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 302 is 1

Notice that 1 = HCF(302,1) .
