HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 845, 124 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 845, 124 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 845, 124 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 845, 124 is 1.

HCF(845, 124) = 1

Highest common factor (HCF) of 845, 124 is 1.

Highest Common Factor of 845,124 using Euclid's algorithm

Highest Common Factor of 845,124 is 1

Step 1: Since 845 > 124, we apply the division lemma to 845 and 124, to get

845 = 124 x 6 + 101

Step 2: Since the reminder 124 ≠ 0, we apply division lemma to 101 and 124, to get

124 = 101 x 1 + 23

Step 3: We consider the new divisor 101 and the new remainder 23, and apply the division lemma to get

101 = 23 x 4 + 9

We consider the new divisor 23 and the new remainder 9,and apply the division lemma to get

23 = 9 x 2 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 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 845 and 124 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(23,9) = HCF(101,23) = HCF(124,101) = HCF(845,124) .
