HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 654, 889, 318 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 654, 889, 318 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 654, 889, 318 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 654, 889, 318 is 1.

HCF(654, 889, 318) = 1

HCF of 654, 889, 318 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 654, 889, 318 is 1.

Highest Common Factor of 654,889,318 using Euclid's algorithm

Highest Common Factor of 654,889,318 is 1

Step 1: Since 889 > 654, we apply the division lemma to 889 and 654, to get

889 = 654 x 1 + 235

Step 2: Since the reminder 654 ≠ 0, we apply division lemma to 235 and 654, to get

654 = 235 x 2 + 184

Step 3: We consider the new divisor 235 and the new remainder 184, and apply the division lemma to get

235 = 184 x 1 + 51

We consider the new divisor 184 and the new remainder 51,and apply the division lemma to get

184 = 51 x 3 + 31

We consider the new divisor 51 and the new remainder 31,and apply the division lemma to get

51 = 31 x 1 + 20

We consider the new divisor 31 and the new remainder 20,and apply the division lemma to get

31 = 20 x 1 + 11

We consider the new divisor 20 and the new remainder 11,and apply the division lemma to get

20 = 11 x 1 + 9

We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get

11 = 9 x 1 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 654 and 889 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(20,11) = HCF(31,20) = HCF(51,31) = HCF(184,51) = HCF(235,184) = HCF(654,235) = HCF(889,654) .

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

Step 1: Since 318 > 1, we apply the division lemma to 318 and 1, to get

318 = 1 x 318 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 318 is 1

Notice that 1 = HCF(318,1) .
