HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1558, 1718 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 1558, 1718 is 2 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 1558, 1718 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 1558, 1718 is 2.

HCF(1558, 1718) = 2

Highest common factor (HCF) of 1558, 1718 is 2.

Highest Common Factor of 1558,1718 using Euclid's algorithm

Highest Common Factor of 1558,1718 is 2

Step 1: Since 1718 > 1558, we apply the division lemma to 1718 and 1558, to get

1718 = 1558 x 1 + 160

Step 2: Since the reminder 1558 ≠ 0, we apply division lemma to 160 and 1558, to get

1558 = 160 x 9 + 118

Step 3: We consider the new divisor 160 and the new remainder 118, and apply the division lemma to get

160 = 118 x 1 + 42

We consider the new divisor 118 and the new remainder 42,and apply the division lemma to get

118 = 42 x 2 + 34

We consider the new divisor 42 and the new remainder 34,and apply the division lemma to get

42 = 34 x 1 + 8

We consider the new divisor 34 and the new remainder 8,and apply the division lemma to get

34 = 8 x 4 + 2

We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get

8 = 2 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 1558 and 1718 is 2

Notice that 2 = HCF(8,2) = HCF(34,8) = HCF(42,34) = HCF(118,42) = HCF(160,118) = HCF(1558,160) = HCF(1718,1558) .
