HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 90, 570, 628 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 90, 570, 628 is 2 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 90, 570, 628 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 90, 570, 628 is 2.

HCF(90, 570, 628) = 2

HCF of 90, 570, 628 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 90, 570, 628 is 2.

Highest Common Factor of 90,570,628 using Euclid's algorithm

Highest Common Factor of 90,570,628 is 2

Step 1: Since 570 > 90, we apply the division lemma to 570 and 90, to get

570 = 90 x 6 + 30

Step 2: Since the reminder 90 ≠ 0, we apply division lemma to 30 and 90, to get

90 = 30 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 30, the HCF of 90 and 570 is 30

Notice that 30 = HCF(90,30) = HCF(570,90) .


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

Step 1: Since 628 > 30, we apply the division lemma to 628 and 30, to get

628 = 30 x 20 + 28

Step 2: Since the reminder 30 ≠ 0, we apply division lemma to 28 and 30, to get

30 = 28 x 1 + 2

Step 3: We consider the new divisor 28 and the new remainder 2, and apply the division lemma to get

28 = 2 x 14 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 30 and 628 is 2

Notice that 2 = HCF(28,2) = HCF(30,28) = HCF(628,30) .
