HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 728, 961, 603, 115 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 728, 961, 603, 115 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 728, 961, 603, 115 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 728, 961, 603, 115 is 1.

HCF(728, 961, 603, 115) = 1

Highest Common Factor of 728,961,603,115 using Euclid's algorithm

Highest Common Factor of 728,961,603,115 is 1

Step 1: Since 961 > 728, we apply the division lemma to 961 and 728, to get

961 = 728 x 1 + 233

Step 2: Since the reminder 728 ≠ 0, we apply division lemma to 233 and 728, to get

728 = 233 x 3 + 29

Step 3: We consider the new divisor 233 and the new remainder 29, and apply the division lemma to get

233 = 29 x 8 + 1

We consider the new divisor 29 and the new remainder 1, and apply the division lemma to get

29 = 1 x 29 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 728 and 961 is 1

Notice that 1 = HCF(29,1) = HCF(233,29) = HCF(728,233) = HCF(961,728) .


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

Step 1: Since 603 > 1, we apply the division lemma to 603 and 1, to get

603 = 1 x 603 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 603 is 1

Notice that 1 = HCF(603,1) .


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

Step 1: Since 115 > 1, we apply the division lemma to 115 and 1, to get

115 = 1 x 115 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 115 is 1

Notice that 1 = HCF(115,1) .
