HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 605, 495, 280 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 605, 495, 280 is 5 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 605, 495, 280 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 605, 495, 280 is 5.

HCF(605, 495, 280) = 5

HCF of 605, 495, 280 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 605, 495, 280 is 5.

Highest Common Factor of 605,495,280 using Euclid's algorithm

Highest Common Factor of 605,495,280 is 5

Step 1: Since 605 > 495, we apply the division lemma to 605 and 495, to get

605 = 495 x 1 + 110

Step 2: Since the reminder 495 ≠ 0, we apply division lemma to 110 and 495, to get

495 = 110 x 4 + 55

Step 3: We consider the new divisor 110 and the new remainder 55, and apply the division lemma to get

110 = 55 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 55, the HCF of 605 and 495 is 55

Notice that 55 = HCF(110,55) = HCF(495,110) = HCF(605,495) .


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

Step 1: Since 280 > 55, we apply the division lemma to 280 and 55, to get

280 = 55 x 5 + 5

Step 2: Since the reminder 55 ≠ 0, we apply division lemma to 5 and 55, to get

55 = 5 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 55 and 280 is 5

Notice that 5 = HCF(55,5) = HCF(280,55) .
