HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 687, 555, 321, 282 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 687, 555, 321, 282 is 3 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 687, 555, 321, 282 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 687, 555, 321, 282 is 3.

HCF(687, 555, 321, 282) = 3

Highest Common Factor of 687,555,321,282 using Euclid's algorithm

Highest Common Factor of 687,555,321,282 is 3

Step 1: Since 687 > 555, we apply the division lemma to 687 and 555, to get

687 = 555 x 1 + 132

Step 2: Since the reminder 555 ≠ 0, we apply division lemma to 132 and 555, to get

555 = 132 x 4 + 27

Step 3: We consider the new divisor 132 and the new remainder 27, and apply the division lemma to get

132 = 27 x 4 + 24

We consider the new divisor 27 and the new remainder 24,and apply the division lemma to get

27 = 24 x 1 + 3

We consider the new divisor 24 and the new remainder 3,and apply the division lemma to get

24 = 3 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 687 and 555 is 3

Notice that 3 = HCF(24,3) = HCF(27,24) = HCF(132,27) = HCF(555,132) = HCF(687,555) .


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

Step 1: Since 321 > 3, we apply the division lemma to 321 and 3, to get

321 = 3 x 107 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 321 is 3

Notice that 3 = HCF(321,3) .


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

Step 1: Since 282 > 3, we apply the division lemma to 282 and 3, to get

282 = 3 x 94 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 282 is 3

Notice that 3 = HCF(282,3) .
