HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 423, 160 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 423, 160 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 423, 160 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 423, 160 is 1.

HCF(423, 160) = 1

Highest common factor (HCF) of 423, 160 is 1.

Highest Common Factor of 423,160 using Euclid's algorithm

Highest Common Factor of 423,160 is 1

Step 1: Since 423 > 160, we apply the division lemma to 423 and 160, to get

423 = 160 x 2 + 103

Step 2: Since the reminder 160 ≠ 0, we apply division lemma to 103 and 160, to get

160 = 103 x 1 + 57

Step 3: We consider the new divisor 103 and the new remainder 57, and apply the division lemma to get

103 = 57 x 1 + 46

We consider the new divisor 57 and the new remainder 46,and apply the division lemma to get

57 = 46 x 1 + 11

We consider the new divisor 46 and the new remainder 11,and apply the division lemma to get

46 = 11 x 4 + 2

We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get

11 = 2 x 5 + 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 423 and 160 is 1

Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(46,11) = HCF(57,46) = HCF(103,57) = HCF(160,103) = HCF(423,160) .
