HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 369, 930 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 369, 930 is 3 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 369, 930 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 369, 930 is 3.

HCF(369, 930) = 3

Highest common factor (HCF) of 369, 930 is 3.

Highest Common Factor of 369,930 using Euclid's algorithm

Highest Common Factor of 369,930 is 3

Step 1: Since 930 > 369, we apply the division lemma to 930 and 369, to get

930 = 369 x 2 + 192

Step 2: Since the reminder 369 ≠ 0, we apply division lemma to 192 and 369, to get

369 = 192 x 1 + 177

Step 3: We consider the new divisor 192 and the new remainder 177, and apply the division lemma to get

192 = 177 x 1 + 15

We consider the new divisor 177 and the new remainder 15,and apply the division lemma to get

177 = 15 x 11 + 12

We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get

15 = 12 x 1 + 3

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

12 = 3 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 369 and 930 is 3

Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(177,15) = HCF(192,177) = HCF(369,192) = HCF(930,369) .
