HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 980, 578, 469, 457 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 980, 578, 469, 457 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 980, 578, 469, 457 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 980, 578, 469, 457 is 1.

HCF(980, 578, 469, 457) = 1

Highest Common Factor of 980,578,469,457 using Euclid's algorithm

Highest Common Factor of 980,578,469,457 is 1

Step 1: Since 980 > 578, we apply the division lemma to 980 and 578, to get

980 = 578 x 1 + 402

Step 2: Since the reminder 578 ≠ 0, we apply division lemma to 402 and 578, to get

578 = 402 x 1 + 176

Step 3: We consider the new divisor 402 and the new remainder 176, and apply the division lemma to get

402 = 176 x 2 + 50

We consider the new divisor 176 and the new remainder 50,and apply the division lemma to get

176 = 50 x 3 + 26

We consider the new divisor 50 and the new remainder 26,and apply the division lemma to get

50 = 26 x 1 + 24

We consider the new divisor 26 and the new remainder 24,and apply the division lemma to get

26 = 24 x 1 + 2

We consider the new divisor 24 and the new remainder 2,and apply the division lemma to get

24 = 2 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 980 and 578 is 2

Notice that 2 = HCF(24,2) = HCF(26,24) = HCF(50,26) = HCF(176,50) = HCF(402,176) = HCF(578,402) = HCF(980,578) .

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

Step 1: Since 469 > 2, we apply the division lemma to 469 and 2, to get

469 = 2 x 234 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 469 is 1

Notice that 1 = HCF(2,1) = HCF(469,2) .

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

Step 1: Since 457 > 1, we apply the division lemma to 457 and 1, to get

457 = 1 x 457 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 457 is 1

Notice that 1 = HCF(457,1) .
