HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 774, 828, 824 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 774, 828, 824 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 774, 828, 824 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 774, 828, 824 is 2.
HCF(774, 828, 824) = 2
HCF of 774, 828, 824 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 774, 828, 824 is 2.
Highest Common Factor of 774,828,824 is 2
Step 1: Since 828 > 774, we apply the division lemma to 828 and 774, to get
828 = 774 x 1 + 54
Step 2: Since the reminder 774 ≠ 0, we apply division lemma to 54 and 774, to get
774 = 54 x 14 + 18
Step 3: We consider the new divisor 54 and the new remainder 18, and apply the division lemma to get
54 = 18 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 774 and 828 is 18
Notice that 18 = HCF(54,18) = HCF(774,54) = HCF(828,774) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 824 > 18, we apply the division lemma to 824 and 18, to get
824 = 18 x 45 + 14
Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 14 and 18, to get
18 = 14 x 1 + 4
Step 3: We consider the new divisor 14 and the new remainder 4, and apply the division lemma to get
14 = 4 x 3 + 2
We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 18 and 824 is 2
Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(18,14) = HCF(824,18) .
