HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 918, 573, 305 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 918, 573, 305 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 918, 573, 305 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 918, 573, 305 is 1.

HCF(918, 573, 305) = 1

Highest Common Factor of 918,573,305 using Euclid's algorithm

Highest Common Factor of 918,573,305 is 1

Step 1: Since 918 > 573, we apply the division lemma to 918 and 573, to get

918 = 573 x 1 + 345

Step 2: Since the reminder 573 ≠ 0, we apply division lemma to 345 and 573, to get

573 = 345 x 1 + 228

Step 3: We consider the new divisor 345 and the new remainder 228, and apply the division lemma to get

345 = 228 x 1 + 117

We consider the new divisor 228 and the new remainder 117,and apply the division lemma to get

228 = 117 x 1 + 111

We consider the new divisor 117 and the new remainder 111,and apply the division lemma to get

117 = 111 x 1 + 6

We consider the new divisor 111 and the new remainder 6,and apply the division lemma to get

111 = 6 x 18 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 918 and 573 is 3

Notice that 3 = HCF(6,3) = HCF(111,6) = HCF(117,111) = HCF(228,117) = HCF(345,228) = HCF(573,345) = HCF(918,573) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 305 > 3, we apply the division lemma to 305 and 3, to get

305 = 3 x 101 + 2

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get

3 = 2 x 1 + 1

Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 305 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(305,3) .
