HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 920, 999 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 920, 999 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 920, 999 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 920, 999 is 1.

HCF(920, 999) = 1

Highest Common Factor of 920,999 using Euclid's algorithm

Highest Common Factor of 920,999 is 1

Step 1: Since 999 > 920, we apply the division lemma to 999 and 920, to get

999 = 920 x 1 + 79

Step 2: Since the reminder 920 ≠ 0, we apply division lemma to 79 and 920, to get

920 = 79 x 11 + 51

Step 3: We consider the new divisor 79 and the new remainder 51, and apply the division lemma to get

79 = 51 x 1 + 28

We consider the new divisor 51 and the new remainder 28,and apply the division lemma to get

51 = 28 x 1 + 23

We consider the new divisor 28 and the new remainder 23,and apply the division lemma to get

28 = 23 x 1 + 5

We consider the new divisor 23 and the new remainder 5,and apply the division lemma to get

23 = 5 x 4 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 920 and 999 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(23,5) = HCF(28,23) = HCF(51,28) = HCF(79,51) = HCF(920,79) = HCF(999,920) .
