HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 718, 920 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 718, 920 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 718, 920 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 718, 920 is 2.

HCF(718, 920) = 2

Highest common factor (HCF) of 718, 920 is 2.

Highest Common Factor of 718,920 using Euclid's algorithm

Highest Common Factor of 718,920 is 2

Step 1: Since 920 > 718, we apply the division lemma to 920 and 718, to get

920 = 718 x 1 + 202

Step 2: Since the reminder 718 ≠ 0, we apply division lemma to 202 and 718, to get

718 = 202 x 3 + 112

Step 3: We consider the new divisor 202 and the new remainder 112, and apply the division lemma to get

202 = 112 x 1 + 90

We consider the new divisor 112 and the new remainder 90,and apply the division lemma to get

112 = 90 x 1 + 22

We consider the new divisor 90 and the new remainder 22,and apply the division lemma to get

90 = 22 x 4 + 2

We consider the new divisor 22 and the new remainder 2,and apply the division lemma to get

22 = 2 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 718 and 920 is 2

Notice that 2 = HCF(22,2) = HCF(90,22) = HCF(112,90) = HCF(202,112) = HCF(718,202) = HCF(920,718) .
