HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 90, 211, 705 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 90, 211, 705 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 90, 211, 705 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, 211, 705 is 1.

HCF(90, 211, 705) = 1

HCF of 90, 211, 705 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, 211, 705 is 1.

Highest Common Factor of 90,211,705 using Euclid's algorithm

Highest Common Factor of 90,211,705 is 1

Step 1: Since 211 > 90, we apply the division lemma to 211 and 90, to get

211 = 90 x 2 + 31

Step 2: Since the reminder 90 ≠ 0, we apply division lemma to 31 and 90, to get

90 = 31 x 2 + 28

Step 3: We consider the new divisor 31 and the new remainder 28, and apply the division lemma to get

31 = 28 x 1 + 3

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

28 = 3 x 9 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 90 and 211 is 1

Notice that 1 = HCF(3,1) = HCF(28,3) = HCF(31,28) = HCF(90,31) = HCF(211,90) .


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

Step 1: Since 705 > 1, we apply the division lemma to 705 and 1, to get

705 = 1 x 705 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 705 is 1

Notice that 1 = HCF(705,1) .
