HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 308, 784, 736, 731 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 308, 784, 736, 731 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 308, 784, 736, 731 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 308, 784, 736, 731 is 1.
HCF(308, 784, 736, 731) = 1
HCF of 308, 784, 736, 731 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 308, 784, 736, 731 is 1.
Highest Common Factor of 308,784,736,731 is 1
Step 1: Since 784 > 308, we apply the division lemma to 784 and 308, to get
784 = 308 x 2 + 168
Step 2: Since the reminder 308 ≠ 0, we apply division lemma to 168 and 308, to get
308 = 168 x 1 + 140
Step 3: We consider the new divisor 168 and the new remainder 140, and apply the division lemma to get
168 = 140 x 1 + 28
We consider the new divisor 140 and the new remainder 28, and apply the division lemma to get
140 = 28 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 28, the HCF of 308 and 784 is 28
Notice that 28 = HCF(140,28) = HCF(168,140) = HCF(308,168) = HCF(784,308) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 736 > 28, we apply the division lemma to 736 and 28, to get
736 = 28 x 26 + 8
Step 2: Since the reminder 28 ≠ 0, we apply division lemma to 8 and 28, to get
28 = 8 x 3 + 4
Step 3: 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 28 and 736 is 4
Notice that 4 = HCF(8,4) = HCF(28,8) = HCF(736,28) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 731 > 4, we apply the division lemma to 731 and 4, to get
731 = 4 x 182 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 731 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(731,4) .
