HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 724, 458, 850 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 724, 458, 850 is 2 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 724, 458, 850 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 724, 458, 850 is 2.

HCF(724, 458, 850) = 2

HCF of 724, 458, 850 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 724, 458, 850 is 2.

Highest Common Factor of 724,458,850 using Euclid's algorithm

Highest Common Factor of 724,458,850 is 2

Step 1: Since 724 > 458, we apply the division lemma to 724 and 458, to get

724 = 458 x 1 + 266

Step 2: Since the reminder 458 ≠ 0, we apply division lemma to 266 and 458, to get

458 = 266 x 1 + 192

Step 3: We consider the new divisor 266 and the new remainder 192, and apply the division lemma to get

266 = 192 x 1 + 74

We consider the new divisor 192 and the new remainder 74,and apply the division lemma to get

192 = 74 x 2 + 44

We consider the new divisor 74 and the new remainder 44,and apply the division lemma to get

74 = 44 x 1 + 30

We consider the new divisor 44 and the new remainder 30,and apply the division lemma to get

44 = 30 x 1 + 14

We consider the new divisor 30 and the new remainder 14,and apply the division lemma to get

30 = 14 x 2 + 2

We consider the new divisor 14 and the new remainder 2,and apply the division lemma to get

14 = 2 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 724 and 458 is 2

Notice that 2 = HCF(14,2) = HCF(30,14) = HCF(44,30) = HCF(74,44) = HCF(192,74) = HCF(266,192) = HCF(458,266) = HCF(724,458) .

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

Step 1: Since 850 > 2, we apply the division lemma to 850 and 2, to get

850 = 2 x 425 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 850 is 2

Notice that 2 = HCF(850,2) .
