HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 520, 719 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 520, 719 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 520, 719 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 520, 719 is 1.

HCF(520, 719) = 1

Highest common factor (HCF) of 520, 719 is 1.

Highest Common Factor of 520,719 using Euclid's algorithm

Highest Common Factor of 520,719 is 1

Step 1: Since 719 > 520, we apply the division lemma to 719 and 520, to get

719 = 520 x 1 + 199

Step 2: Since the reminder 520 ≠ 0, we apply division lemma to 199 and 520, to get

520 = 199 x 2 + 122

Step 3: We consider the new divisor 199 and the new remainder 122, and apply the division lemma to get

199 = 122 x 1 + 77

We consider the new divisor 122 and the new remainder 77,and apply the division lemma to get

122 = 77 x 1 + 45

We consider the new divisor 77 and the new remainder 45,and apply the division lemma to get

77 = 45 x 1 + 32

We consider the new divisor 45 and the new remainder 32,and apply the division lemma to get

45 = 32 x 1 + 13

We consider the new divisor 32 and the new remainder 13,and apply the division lemma to get

32 = 13 x 2 + 6

We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get

13 = 6 x 2 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 520 and 719 is 1

Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(32,13) = HCF(45,32) = HCF(77,45) = HCF(122,77) = HCF(199,122) = HCF(520,199) = HCF(719,520) .
