HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 504, 68939 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 504, 68939 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 504, 68939 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 504, 68939 is 1.

HCF(504, 68939) = 1

Highest common factor (HCF) of 504, 68939 is 1.

Highest Common Factor of 504,68939 using Euclid's algorithm

Highest Common Factor of 504,68939 is 1

Step 1: Since 68939 > 504, we apply the division lemma to 68939 and 504, to get

68939 = 504 x 136 + 395

Step 2: Since the reminder 504 ≠ 0, we apply division lemma to 395 and 504, to get

504 = 395 x 1 + 109

Step 3: We consider the new divisor 395 and the new remainder 109, and apply the division lemma to get

395 = 109 x 3 + 68

We consider the new divisor 109 and the new remainder 68,and apply the division lemma to get

109 = 68 x 1 + 41

We consider the new divisor 68 and the new remainder 41,and apply the division lemma to get

68 = 41 x 1 + 27

We consider the new divisor 41 and the new remainder 27,and apply the division lemma to get

41 = 27 x 1 + 14

We consider the new divisor 27 and the new remainder 14,and apply the division lemma to get

27 = 14 x 1 + 13

We consider the new divisor 14 and the new remainder 13,and apply the division lemma to get

14 = 13 x 1 + 1

We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get

13 = 1 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 504 and 68939 is 1

Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(27,14) = HCF(41,27) = HCF(68,41) = HCF(109,68) = HCF(395,109) = HCF(504,395) = HCF(68939,504) .
