HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 769, 20240 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 769, 20240 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 769, 20240 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 769, 20240 is 1.

HCF(769, 20240) = 1

Highest common factor (HCF) of 769, 20240 is 1.

Highest Common Factor of 769,20240 using Euclid's algorithm

Highest Common Factor of 769,20240 is 1

Step 1: Since 20240 > 769, we apply the division lemma to 20240 and 769, to get

20240 = 769 x 26 + 246

Step 2: Since the reminder 769 ≠ 0, we apply division lemma to 246 and 769, to get

769 = 246 x 3 + 31

Step 3: We consider the new divisor 246 and the new remainder 31, and apply the division lemma to get

246 = 31 x 7 + 29

We consider the new divisor 31 and the new remainder 29,and apply the division lemma to get

31 = 29 x 1 + 2

We consider the new divisor 29 and the new remainder 2,and apply the division lemma to get

29 = 2 x 14 + 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 769 and 20240 is 1

Notice that 1 = HCF(2,1) = HCF(29,2) = HCF(31,29) = HCF(246,31) = HCF(769,246) = HCF(20240,769) .
