HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 774, 999, 474, 180 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 774, 999, 474, 180 is 3 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, 999, 474, 180 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, 999, 474, 180 is 3.
HCF(774, 999, 474, 180) = 3
HCF of 774, 999, 474, 180 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, 999, 474, 180 is 3.
Highest Common Factor of 774,999,474,180 is 3
Step 1: Since 999 > 774, we apply the division lemma to 999 and 774, to get
999 = 774 x 1 + 225
Step 2: Since the reminder 774 ≠ 0, we apply division lemma to 225 and 774, to get
774 = 225 x 3 + 99
Step 3: We consider the new divisor 225 and the new remainder 99, and apply the division lemma to get
225 = 99 x 2 + 27
We consider the new divisor 99 and the new remainder 27,and apply the division lemma to get
99 = 27 x 3 + 18
We consider the new divisor 27 and the new remainder 18,and apply the division lemma to get
27 = 18 x 1 + 9
We consider the new divisor 18 and the new remainder 9,and apply the division lemma to get
18 = 9 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 774 and 999 is 9
Notice that 9 = HCF(18,9) = HCF(27,18) = HCF(99,27) = HCF(225,99) = HCF(774,225) = HCF(999,774) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 474 > 9, we apply the division lemma to 474 and 9, to get
474 = 9 x 52 + 6
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 6 and 9, to get
9 = 6 x 1 + 3
Step 3: We consider the new divisor 6 and the new remainder 3, and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 9 and 474 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(474,9) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 180 > 3, we apply the division lemma to 180 and 3, to get
180 = 3 x 60 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 180 is 3
Notice that 3 = HCF(180,3) .
