HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 489, 703, 562 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 489, 703, 562 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 489, 703, 562 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 489, 703, 562 is 1.

HCF(489, 703, 562) = 1

Highest common factor (HCF) of 489, 703, 562 is 1.

Highest Common Factor of 489,703,562 using Euclid's algorithm

Highest Common Factor of 489,703,562 is 1

Step 1: Since 703 > 489, we apply the division lemma to 703 and 489, to get

703 = 489 x 1 + 214

Step 2: Since the reminder 489 ≠ 0, we apply division lemma to 214 and 489, to get

489 = 214 x 2 + 61

Step 3: We consider the new divisor 214 and the new remainder 61, and apply the division lemma to get

214 = 61 x 3 + 31

We consider the new divisor 61 and the new remainder 31,and apply the division lemma to get

61 = 31 x 1 + 30

We consider the new divisor 31 and the new remainder 30,and apply the division lemma to get

31 = 30 x 1 + 1

We consider the new divisor 30 and the new remainder 1,and apply the division lemma to get

30 = 1 x 30 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 489 and 703 is 1

Notice that 1 = HCF(30,1) = HCF(31,30) = HCF(61,31) = HCF(214,61) = HCF(489,214) = HCF(703,489) .

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

Step 1: Since 562 > 1, we apply the division lemma to 562 and 1, to get

562 = 1 x 562 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 562 is 1

Notice that 1 = HCF(562,1) .
