HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 609, 354, 988 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 609, 354, 988 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 609, 354, 988 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 609, 354, 988 is 1.

HCF(609, 354, 988) = 1

Highest common factor (HCF) of 609, 354, 988 is 1.

Highest Common Factor of 609,354,988 using Euclid's algorithm

Highest Common Factor of 609,354,988 is 1

Step 1: Since 609 > 354, we apply the division lemma to 609 and 354, to get

609 = 354 x 1 + 255

Step 2: Since the reminder 354 ≠ 0, we apply division lemma to 255 and 354, to get

354 = 255 x 1 + 99

Step 3: We consider the new divisor 255 and the new remainder 99, and apply the division lemma to get

255 = 99 x 2 + 57

We consider the new divisor 99 and the new remainder 57,and apply the division lemma to get

99 = 57 x 1 + 42

We consider the new divisor 57 and the new remainder 42,and apply the division lemma to get

57 = 42 x 1 + 15

We consider the new divisor 42 and the new remainder 15,and apply the division lemma to get

42 = 15 x 2 + 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 609 and 354 is 3

Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(42,15) = HCF(57,42) = HCF(99,57) = HCF(255,99) = HCF(354,255) = HCF(609,354) .


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

Step 1: Since 988 > 3, we apply the division lemma to 988 and 3, to get

988 = 3 x 329 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 988 is 1

Notice that 1 = HCF(3,1) = HCF(988,3) .
