HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 750, 289, 861 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 750, 289, 861 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 750, 289, 861 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 750, 289, 861 is 1.

HCF(750, 289, 861) = 1

Highest common factor (HCF) of 750, 289, 861 is 1.

Highest Common Factor of 750,289,861 using Euclid's algorithm

Highest Common Factor of 750,289,861 is 1

Step 1: Since 750 > 289, we apply the division lemma to 750 and 289, to get

750 = 289 x 2 + 172

Step 2: Since the reminder 289 ≠ 0, we apply division lemma to 172 and 289, to get

289 = 172 x 1 + 117

Step 3: We consider the new divisor 172 and the new remainder 117, and apply the division lemma to get

172 = 117 x 1 + 55

We consider the new divisor 117 and the new remainder 55,and apply the division lemma to get

117 = 55 x 2 + 7

We consider the new divisor 55 and the new remainder 7,and apply the division lemma to get

55 = 7 x 7 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 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 750 and 289 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(55,7) = HCF(117,55) = HCF(172,117) = HCF(289,172) = HCF(750,289) .

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

Step 1: Since 861 > 1, we apply the division lemma to 861 and 1, to get

861 = 1 x 861 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 861 is 1

Notice that 1 = HCF(861,1) .
