HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 720, 627, 898 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 720, 627, 898 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 720, 627, 898 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 720, 627, 898 is 1.

HCF(720, 627, 898) = 1

Highest common factor (HCF) of 720, 627, 898 is 1.

Highest Common Factor of 720,627,898 using Euclid's algorithm

Highest Common Factor of 720,627,898 is 1

Step 1: Since 720 > 627, we apply the division lemma to 720 and 627, to get

720 = 627 x 1 + 93

Step 2: Since the reminder 627 ≠ 0, we apply division lemma to 93 and 627, to get

627 = 93 x 6 + 69

Step 3: We consider the new divisor 93 and the new remainder 69, and apply the division lemma to get

93 = 69 x 1 + 24

We consider the new divisor 69 and the new remainder 24,and apply the division lemma to get

69 = 24 x 2 + 21

We consider the new divisor 24 and the new remainder 21,and apply the division lemma to get

24 = 21 x 1 + 3

We consider the new divisor 21 and the new remainder 3,and apply the division lemma to get

21 = 3 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 720 and 627 is 3

Notice that 3 = HCF(21,3) = HCF(24,21) = HCF(69,24) = HCF(93,69) = HCF(627,93) = HCF(720,627) .

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

Step 1: Since 898 > 3, we apply the division lemma to 898 and 3, to get

898 = 3 x 299 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 898 is 1

Notice that 1 = HCF(3,1) = HCF(898,3) .
