HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 440, 681 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 440, 681 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 440, 681 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 440, 681 is 1.

HCF(440, 681) = 1

Highest Common Factor of 440,681 using Euclid's algorithm

Highest Common Factor of 440,681 is 1

Step 1: Since 681 > 440, we apply the division lemma to 681 and 440, to get

681 = 440 x 1 + 241

Step 2: Since the reminder 440 ≠ 0, we apply division lemma to 241 and 440, to get

440 = 241 x 1 + 199

Step 3: We consider the new divisor 241 and the new remainder 199, and apply the division lemma to get

241 = 199 x 1 + 42

We consider the new divisor 199 and the new remainder 42,and apply the division lemma to get

199 = 42 x 4 + 31

We consider the new divisor 42 and the new remainder 31,and apply the division lemma to get

42 = 31 x 1 + 11

We consider the new divisor 31 and the new remainder 11,and apply the division lemma to get

31 = 11 x 2 + 9

We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get

11 = 9 x 1 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 1

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 440 and 681 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(31,11) = HCF(42,31) = HCF(199,42) = HCF(241,199) = HCF(440,241) = HCF(681,440) .
