HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 494, 798, 828 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 494, 798, 828 is 2 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 494, 798, 828 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 494, 798, 828 is 2.
HCF(494, 798, 828) = 2
HCF of 494, 798, 828 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 494, 798, 828 is 2.
Highest Common Factor of 494,798,828 is 2
Step 1: Since 798 > 494, we apply the division lemma to 798 and 494, to get
798 = 494 x 1 + 304
Step 2: Since the reminder 494 ≠ 0, we apply division lemma to 304 and 494, to get
494 = 304 x 1 + 190
Step 3: We consider the new divisor 304 and the new remainder 190, and apply the division lemma to get
304 = 190 x 1 + 114
We consider the new divisor 190 and the new remainder 114,and apply the division lemma to get
190 = 114 x 1 + 76
We consider the new divisor 114 and the new remainder 76,and apply the division lemma to get
114 = 76 x 1 + 38
We consider the new divisor 76 and the new remainder 38,and apply the division lemma to get
76 = 38 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 38, the HCF of 494 and 798 is 38
Notice that 38 = HCF(76,38) = HCF(114,76) = HCF(190,114) = HCF(304,190) = HCF(494,304) = HCF(798,494) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 828 > 38, we apply the division lemma to 828 and 38, to get
828 = 38 x 21 + 30
Step 2: Since the reminder 38 ≠ 0, we apply division lemma to 30 and 38, to get
38 = 30 x 1 + 8
Step 3: We consider the new divisor 30 and the new remainder 8, and apply the division lemma to get
30 = 8 x 3 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 38 and 828 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(30,8) = HCF(38,30) = HCF(828,38) .
