HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 829, 955, 778 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 829, 955, 778 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 829, 955, 778 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 829, 955, 778 is 1.
HCF(829, 955, 778) = 1
HCF of 829, 955, 778 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 829, 955, 778 is 1.
Highest Common Factor of 829,955,778 is 1
Step 1: Since 955 > 829, we apply the division lemma to 955 and 829, to get
955 = 829 x 1 + 126
Step 2: Since the reminder 829 ≠ 0, we apply division lemma to 126 and 829, to get
829 = 126 x 6 + 73
Step 3: We consider the new divisor 126 and the new remainder 73, and apply the division lemma to get
126 = 73 x 1 + 53
We consider the new divisor 73 and the new remainder 53,and apply the division lemma to get
73 = 53 x 1 + 20
We consider the new divisor 53 and the new remainder 20,and apply the division lemma to get
53 = 20 x 2 + 13
We consider the new divisor 20 and the new remainder 13,and apply the division lemma to get
20 = 13 x 1 + 7
We consider the new divisor 13 and the new remainder 7,and apply the division lemma to get
13 = 7 x 1 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 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 829 and 955 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(13,7) = HCF(20,13) = HCF(53,20) = HCF(73,53) = HCF(126,73) = HCF(829,126) = HCF(955,829) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 778 > 1, we apply the division lemma to 778 and 1, to get
778 = 1 x 778 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 778 is 1
Notice that 1 = HCF(778,1) .
