HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 990, 697, 263, 475 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 990, 697, 263, 475 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 990, 697, 263, 475 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 990, 697, 263, 475 is 1.

HCF(990, 697, 263, 475) = 1

Highest common factor (HCF) of 990, 697, 263, 475 is 1.

Highest Common Factor of 990,697,263,475 using Euclid's algorithm

Highest Common Factor of 990,697,263,475 is 1

Step 1: Since 990 > 697, we apply the division lemma to 990 and 697, to get

990 = 697 x 1 + 293

Step 2: Since the reminder 697 ≠ 0, we apply division lemma to 293 and 697, to get

697 = 293 x 2 + 111

Step 3: We consider the new divisor 293 and the new remainder 111, and apply the division lemma to get

293 = 111 x 2 + 71

We consider the new divisor 111 and the new remainder 71,and apply the division lemma to get

111 = 71 x 1 + 40

We consider the new divisor 71 and the new remainder 40,and apply the division lemma to get

71 = 40 x 1 + 31

We consider the new divisor 40 and the new remainder 31,and apply the division lemma to get

40 = 31 x 1 + 9

We consider the new divisor 31 and the new remainder 9,and apply the division lemma to get

31 = 9 x 3 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 990 and 697 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(31,9) = HCF(40,31) = HCF(71,40) = HCF(111,71) = HCF(293,111) = HCF(697,293) = HCF(990,697) .

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

Step 1: Since 263 > 1, we apply the division lemma to 263 and 1, to get

263 = 1 x 263 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 263 is 1

Notice that 1 = HCF(263,1) .

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

Step 1: Since 475 > 1, we apply the division lemma to 475 and 1, to get

475 = 1 x 475 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 475 is 1

Notice that 1 = HCF(475,1) .
