HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 738, 131, 438 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 738, 131, 438 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 738, 131, 438 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 738, 131, 438 is 1.
HCF(738, 131, 438) = 1
HCF of 738, 131, 438 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 738, 131, 438 is 1.
Highest Common Factor of 738,131,438 is 1
Step 1: Since 738 > 131, we apply the division lemma to 738 and 131, to get
738 = 131 x 5 + 83
Step 2: Since the reminder 131 ≠ 0, we apply division lemma to 83 and 131, to get
131 = 83 x 1 + 48
Step 3: We consider the new divisor 83 and the new remainder 48, and apply the division lemma to get
83 = 48 x 1 + 35
We consider the new divisor 48 and the new remainder 35,and apply the division lemma to get
48 = 35 x 1 + 13
We consider the new divisor 35 and the new remainder 13,and apply the division lemma to get
35 = 13 x 2 + 9
We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get
13 = 9 x 1 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 738 and 131 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(35,13) = HCF(48,35) = HCF(83,48) = HCF(131,83) = HCF(738,131) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 438 > 1, we apply the division lemma to 438 and 1, to get
438 = 1 x 438 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 438 is 1
Notice that 1 = HCF(438,1) .
