HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 661, 3688, 4998 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 661, 3688, 4998 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 661, 3688, 4998 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 661, 3688, 4998 is 1.

HCF(661, 3688, 4998) = 1

Highest common factor (HCF) of 661, 3688, 4998 is 1.

Highest Common Factor of 661,3688,4998 using Euclid's algorithm

Highest Common Factor of 661,3688,4998 is 1

Step 1: Since 3688 > 661, we apply the division lemma to 3688 and 661, to get

3688 = 661 x 5 + 383

Step 2: Since the reminder 661 ≠ 0, we apply division lemma to 383 and 661, to get

661 = 383 x 1 + 278

Step 3: We consider the new divisor 383 and the new remainder 278, and apply the division lemma to get

383 = 278 x 1 + 105

We consider the new divisor 278 and the new remainder 105,and apply the division lemma to get

278 = 105 x 2 + 68

We consider the new divisor 105 and the new remainder 68,and apply the division lemma to get

105 = 68 x 1 + 37

We consider the new divisor 68 and the new remainder 37,and apply the division lemma to get

68 = 37 x 1 + 31

We consider the new divisor 37 and the new remainder 31,and apply the division lemma to get

37 = 31 x 1 + 6

We consider the new divisor 31 and the new remainder 6,and apply the division lemma to get

31 = 6 x 5 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 661 and 3688 is 1

Notice that 1 = HCF(6,1) = HCF(31,6) = HCF(37,31) = HCF(68,37) = HCF(105,68) = HCF(278,105) = HCF(383,278) = HCF(661,383) = HCF(3688,661) .


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

Step 1: Since 4998 > 1, we apply the division lemma to 4998 and 1, to get

4998 = 1 x 4998 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 4998 is 1

Notice that 1 = HCF(4998,1) .
