HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 90, 60, 209, 270 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 90, 60, 209, 270 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, 60, 209, 270 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, 60, 209, 270 is 1.

HCF(90, 60, 209, 270) = 1

HCF of 90, 60, 209, 270 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, 60, 209, 270 is 1.

Highest Common Factor of 90,60,209,270 using Euclid's algorithm

Highest Common Factor of 90,60,209,270 is 1

Step 1: Since 90 > 60, we apply the division lemma to 90 and 60, to get

90 = 60 x 1 + 30

Step 2: Since the reminder 60 ≠ 0, we apply division lemma to 30 and 60, to get

60 = 30 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 30, the HCF of 90 and 60 is 30

Notice that 30 = HCF(60,30) = HCF(90,60) .


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

Step 1: Since 209 > 30, we apply the division lemma to 209 and 30, to get

209 = 30 x 6 + 29

Step 2: Since the reminder 30 ≠ 0, we apply division lemma to 29 and 30, to get

30 = 29 x 1 + 1

Step 3: 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 30 and 209 is 1

Notice that 1 = HCF(29,1) = HCF(30,29) = HCF(209,30) .


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

Step 1: Since 270 > 1, we apply the division lemma to 270 and 1, to get

270 = 1 x 270 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 270 is 1

Notice that 1 = HCF(270,1) .
