HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 2545, 3630, 72204 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 2545, 3630, 72204 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 2545, 3630, 72204 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 2545, 3630, 72204 is 1.

HCF(2545, 3630, 72204) = 1

Highest common factor (HCF) of 2545, 3630, 72204 is 1.

Highest Common Factor of 2545,3630,72204 using Euclid's algorithm

Highest Common Factor of 2545,3630,72204 is 1

Step 1: Since 3630 > 2545, we apply the division lemma to 3630 and 2545, to get

3630 = 2545 x 1 + 1085

Step 2: Since the reminder 2545 ≠ 0, we apply division lemma to 1085 and 2545, to get

2545 = 1085 x 2 + 375

Step 3: We consider the new divisor 1085 and the new remainder 375, and apply the division lemma to get

1085 = 375 x 2 + 335

We consider the new divisor 375 and the new remainder 335,and apply the division lemma to get

375 = 335 x 1 + 40

We consider the new divisor 335 and the new remainder 40,and apply the division lemma to get

335 = 40 x 8 + 15

We consider the new divisor 40 and the new remainder 15,and apply the division lemma to get

40 = 15 x 2 + 10

We consider the new divisor 15 and the new remainder 10,and apply the division lemma to get

15 = 10 x 1 + 5

We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get

10 = 5 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 2545 and 3630 is 5

Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(40,15) = HCF(335,40) = HCF(375,335) = HCF(1085,375) = HCF(2545,1085) = HCF(3630,2545) .

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

Step 1: Since 72204 > 5, we apply the division lemma to 72204 and 5, to get

72204 = 5 x 14440 + 4

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get

5 = 4 x 1 + 1

Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 72204 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(72204,5) .
