HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 684, 504, 342 i.e. 18 the largest integer that leaves a remainder zero for all numbers.

HCF of 684, 504, 342 is 18 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 684, 504, 342 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 684, 504, 342 is 18.

HCF(684, 504, 342) = 18

HCF of 684, 504, 342 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 684, 504, 342 is 18.

Highest Common Factor of 684,504,342 using Euclid's algorithm

Highest Common Factor of 684,504,342 is 18

Step 1: Since 684 > 504, we apply the division lemma to 684 and 504, to get

684 = 504 x 1 + 180

Step 2: Since the reminder 504 ≠ 0, we apply division lemma to 180 and 504, to get

504 = 180 x 2 + 144

Step 3: We consider the new divisor 180 and the new remainder 144, and apply the division lemma to get

180 = 144 x 1 + 36

We consider the new divisor 144 and the new remainder 36, and apply the division lemma to get

144 = 36 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 36, the HCF of 684 and 504 is 36

Notice that 36 = HCF(144,36) = HCF(180,144) = HCF(504,180) = HCF(684,504) .


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

Step 1: Since 342 > 36, we apply the division lemma to 342 and 36, to get

342 = 36 x 9 + 18

Step 2: Since the reminder 36 ≠ 0, we apply division lemma to 18 and 36, to get

36 = 18 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 36 and 342 is 18

Notice that 18 = HCF(36,18) = HCF(342,36) .
