HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 785, 24555 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 785, 24555 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 785, 24555 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 785, 24555 is 5.

HCF(785, 24555) = 5

Highest common factor (HCF) of 785, 24555 is 5.

Highest Common Factor of 785,24555 using Euclid's algorithm

Highest Common Factor of 785,24555 is 5

Step 1: Since 24555 > 785, we apply the division lemma to 24555 and 785, to get

24555 = 785 x 31 + 220

Step 2: Since the reminder 785 ≠ 0, we apply division lemma to 220 and 785, to get

785 = 220 x 3 + 125

Step 3: We consider the new divisor 220 and the new remainder 125, and apply the division lemma to get

220 = 125 x 1 + 95

We consider the new divisor 125 and the new remainder 95,and apply the division lemma to get

125 = 95 x 1 + 30

We consider the new divisor 95 and the new remainder 30,and apply the division lemma to get

95 = 30 x 3 + 5

We consider the new divisor 30 and the new remainder 5,and apply the division lemma to get

30 = 5 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 785 and 24555 is 5

Notice that 5 = HCF(30,5) = HCF(95,30) = HCF(125,95) = HCF(220,125) = HCF(785,220) = HCF(24555,785) .
