HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 280, 73, 203, 359 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 280, 73, 203, 359 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 280, 73, 203, 359 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 280, 73, 203, 359 is 1.

HCF(280, 73, 203, 359) = 1

HCF of 280, 73, 203, 359 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 280, 73, 203, 359 is 1.

Highest Common Factor of 280,73,203,359 using Euclid's algorithm

Highest Common Factor of 280,73,203,359 is 1

Step 1: Since 280 > 73, we apply the division lemma to 280 and 73, to get

280 = 73 x 3 + 61

Step 2: Since the reminder 73 ≠ 0, we apply division lemma to 61 and 73, to get

73 = 61 x 1 + 12

Step 3: We consider the new divisor 61 and the new remainder 12, and apply the division lemma to get

61 = 12 x 5 + 1

We consider the new divisor 12 and the new remainder 1, and apply the division lemma to get

12 = 1 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 280 and 73 is 1

Notice that 1 = HCF(12,1) = HCF(61,12) = HCF(73,61) = HCF(280,73) .


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

Step 1: Since 203 > 1, we apply the division lemma to 203 and 1, to get

203 = 1 x 203 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 203 is 1

Notice that 1 = HCF(203,1) .


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

Step 1: Since 359 > 1, we apply the division lemma to 359 and 1, to get

359 = 1 x 359 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 359 is 1

Notice that 1 = HCF(359,1) .
