HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 479, 750, 72 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 479, 750, 72 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 479, 750, 72 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 479, 750, 72 is 1.

HCF(479, 750, 72) = 1

Highest common factor (HCF) of 479, 750, 72 is 1.

Highest Common Factor of 479,750,72 using Euclid's algorithm

Highest Common Factor of 479,750,72 is 1

Step 1: Since 750 > 479, we apply the division lemma to 750 and 479, to get

750 = 479 x 1 + 271

Step 2: Since the reminder 479 ≠ 0, we apply division lemma to 271 and 479, to get

479 = 271 x 1 + 208

Step 3: We consider the new divisor 271 and the new remainder 208, and apply the division lemma to get

271 = 208 x 1 + 63

We consider the new divisor 208 and the new remainder 63,and apply the division lemma to get

208 = 63 x 3 + 19

We consider the new divisor 63 and the new remainder 19,and apply the division lemma to get

63 = 19 x 3 + 6

We consider the new divisor 19 and the new remainder 6,and apply the division lemma to get

19 = 6 x 3 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 479 and 750 is 1

Notice that 1 = HCF(6,1) = HCF(19,6) = HCF(63,19) = HCF(208,63) = HCF(271,208) = HCF(479,271) = HCF(750,479) .

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

Step 1: Since 72 > 1, we apply the division lemma to 72 and 1, to get

72 = 1 x 72 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 72 is 1

Notice that 1 = HCF(72,1) .
