HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 30, 708 i.e. 6 the largest integer that leaves a remainder zero for all numbers.

HCF of 30, 708 is 6 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 30, 708 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 30, 708 is 6.

HCF(30, 708) = 6

Highest common factor (HCF) of 30, 708 is 6.

Highest Common Factor of 30,708 using Euclid's algorithm

Highest Common Factor of 30,708 is 6

Step 1: Since 708 > 30, we apply the division lemma to 708 and 30, to get

708 = 30 x 23 + 18

Step 2: Since the reminder 30 ≠ 0, we apply division lemma to 18 and 30, to get

30 = 18 x 1 + 12

Step 3: We consider the new divisor 18 and the new remainder 12, and apply the division lemma to get

18 = 12 x 1 + 6

We consider the new divisor 12 and the new remainder 6, and apply the division lemma to get

12 = 6 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 30 and 708 is 6

Notice that 6 = HCF(12,6) = HCF(18,12) = HCF(30,18) = HCF(708,30) .
