HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 505, 83520 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 505, 83520 is 5 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 505, 83520 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 505, 83520 is 5.

HCF(505, 83520) = 5

Highest Common Factor of 505,83520 using Euclid's algorithm

Highest Common Factor of 505,83520 is 5

Step 1: Since 83520 > 505, we apply the division lemma to 83520 and 505, to get

83520 = 505 x 165 + 195

Step 2: Since the reminder 505 ≠ 0, we apply division lemma to 195 and 505, to get

505 = 195 x 2 + 115

Step 3: We consider the new divisor 195 and the new remainder 115, and apply the division lemma to get

195 = 115 x 1 + 80

We consider the new divisor 115 and the new remainder 80,and apply the division lemma to get

115 = 80 x 1 + 35

We consider the new divisor 80 and the new remainder 35,and apply the division lemma to get

80 = 35 x 2 + 10

We consider the new divisor 35 and the new remainder 10,and apply the division lemma to get

35 = 10 x 3 + 5

We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get

10 = 5 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 505 and 83520 is 5

Notice that 5 = HCF(10,5) = HCF(35,10) = HCF(80,35) = HCF(115,80) = HCF(195,115) = HCF(505,195) = HCF(83520,505) .
