HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 484, 412, 778, 275 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 484, 412, 778, 275 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 484, 412, 778, 275 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 484, 412, 778, 275 is 1.
HCF(484, 412, 778, 275) = 1
HCF of 484, 412, 778, 275 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 484, 412, 778, 275 is 1.
Highest Common Factor of 484,412,778,275 is 1
Step 1: Since 484 > 412, we apply the division lemma to 484 and 412, to get
484 = 412 x 1 + 72
Step 2: Since the reminder 412 ≠ 0, we apply division lemma to 72 and 412, to get
412 = 72 x 5 + 52
Step 3: We consider the new divisor 72 and the new remainder 52, and apply the division lemma to get
72 = 52 x 1 + 20
We consider the new divisor 52 and the new remainder 20,and apply the division lemma to get
52 = 20 x 2 + 12
We consider the new divisor 20 and the new remainder 12,and apply the division lemma to get
20 = 12 x 1 + 8
We consider the new divisor 12 and the new remainder 8,and apply the division lemma to get
12 = 8 x 1 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 484 and 412 is 4
Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(20,12) = HCF(52,20) = HCF(72,52) = HCF(412,72) = HCF(484,412) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 778 > 4, we apply the division lemma to 778 and 4, to get
778 = 4 x 194 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, 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 4 and 778 is 2
Notice that 2 = HCF(4,2) = HCF(778,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 275 > 2, we apply the division lemma to 275 and 2, to get
275 = 2 x 137 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 275 is 1
Notice that 1 = HCF(2,1) = HCF(275,2) .
