HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 272, 7783, 1028 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 272, 7783, 1028 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 272, 7783, 1028 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 272, 7783, 1028 is 1.

HCF(272, 7783, 1028) = 1

Highest common factor (HCF) of 272, 7783, 1028 is 1.

Highest Common Factor of 272,7783,1028 using Euclid's algorithm

Highest Common Factor of 272,7783,1028 is 1

Step 1: Since 7783 > 272, we apply the division lemma to 7783 and 272, to get

7783 = 272 x 28 + 167

Step 2: Since the reminder 272 ≠ 0, we apply division lemma to 167 and 272, to get

272 = 167 x 1 + 105

Step 3: We consider the new divisor 167 and the new remainder 105, and apply the division lemma to get

167 = 105 x 1 + 62

We consider the new divisor 105 and the new remainder 62,and apply the division lemma to get

105 = 62 x 1 + 43

We consider the new divisor 62 and the new remainder 43,and apply the division lemma to get

62 = 43 x 1 + 19

We consider the new divisor 43 and the new remainder 19,and apply the division lemma to get

43 = 19 x 2 + 5

We consider the new divisor 19 and the new remainder 5,and apply the division lemma to get

19 = 5 x 3 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 272 and 7783 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(19,5) = HCF(43,19) = HCF(62,43) = HCF(105,62) = HCF(167,105) = HCF(272,167) = HCF(7783,272) .

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

Step 1: Since 1028 > 1, we apply the division lemma to 1028 and 1, to get

1028 = 1 x 1028 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 1028 is 1

Notice that 1 = HCF(1028,1) .
