HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 290, 985 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 290, 985 is 5 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 290, 985 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 290, 985 is 5.

HCF(290, 985) = 5

HCF of 290, 985 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 290, 985 is 5.

Highest Common Factor of 290,985 using Euclid's algorithm

Highest Common Factor of 290,985 is 5

Step 1: Since 985 > 290, we apply the division lemma to 985 and 290, to get

985 = 290 x 3 + 115

Step 2: Since the reminder 290 ≠ 0, we apply division lemma to 115 and 290, to get

290 = 115 x 2 + 60

Step 3: We consider the new divisor 115 and the new remainder 60, and apply the division lemma to get

115 = 60 x 1 + 55

We consider the new divisor 60 and the new remainder 55,and apply the division lemma to get

60 = 55 x 1 + 5

We consider the new divisor 55 and the new remainder 5,and apply the division lemma to get

55 = 5 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 290 and 985 is 5

Notice that 5 = HCF(55,5) = HCF(60,55) = HCF(115,60) = HCF(290,115) = HCF(985,290) .
