HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 577, 378, 728 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 577, 378, 728 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 577, 378, 728 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 577, 378, 728 is 1.

HCF(577, 378, 728) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 577, 378, 728 is 1.

Highest Common Factor of 577,378,728 using Euclid's algorithm

Highest Common Factor of 577,378,728 is 1

Step 1: Since 577 > 378, we apply the division lemma to 577 and 378, to get

577 = 378 x 1 + 199

Step 2: Since the reminder 378 ≠ 0, we apply division lemma to 199 and 378, to get

378 = 199 x 1 + 179

Step 3: We consider the new divisor 199 and the new remainder 179, and apply the division lemma to get

199 = 179 x 1 + 20

We consider the new divisor 179 and the new remainder 20,and apply the division lemma to get

179 = 20 x 8 + 19

We consider the new divisor 20 and the new remainder 19,and apply the division lemma to get

20 = 19 x 1 + 1

We consider the new divisor 19 and the new remainder 1,and apply the division lemma to get

19 = 1 x 19 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 577 and 378 is 1

Notice that 1 = HCF(19,1) = HCF(20,19) = HCF(179,20) = HCF(199,179) = HCF(378,199) = HCF(577,378) .

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

Step 1: Since 728 > 1, we apply the division lemma to 728 and 1, to get

728 = 1 x 728 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 728 is 1

Notice that 1 = HCF(728,1) .
