HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 369, 557, 28 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 369, 557, 28 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 369, 557, 28 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 369, 557, 28 is 1.

HCF(369, 557, 28) = 1

Highest common factor (HCF) of 369, 557, 28 is 1.

Highest Common Factor of 369,557,28 using Euclid's algorithm

Highest Common Factor of 369,557,28 is 1

Step 1: Since 557 > 369, we apply the division lemma to 557 and 369, to get

557 = 369 x 1 + 188

Step 2: Since the reminder 369 ≠ 0, we apply division lemma to 188 and 369, to get

369 = 188 x 1 + 181

Step 3: We consider the new divisor 188 and the new remainder 181, and apply the division lemma to get

188 = 181 x 1 + 7

We consider the new divisor 181 and the new remainder 7,and apply the division lemma to get

181 = 7 x 25 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 369 and 557 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(181,7) = HCF(188,181) = HCF(369,188) = HCF(557,369) .

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

Step 1: Since 28 > 1, we apply the division lemma to 28 and 1, to get

28 = 1 x 28 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 28 is 1

Notice that 1 = HCF(28,1) .
