HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 747, 787, 159 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 747, 787, 159 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 747, 787, 159 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 747, 787, 159 is 1.
HCF(747, 787, 159) = 1
HCF of 747, 787, 159 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 747, 787, 159 is 1.
Highest Common Factor of 747,787,159 is 1
Step 1: Since 787 > 747, we apply the division lemma to 787 and 747, to get
787 = 747 x 1 + 40
Step 2: Since the reminder 747 ≠ 0, we apply division lemma to 40 and 747, to get
747 = 40 x 18 + 27
Step 3: We consider the new divisor 40 and the new remainder 27, and apply the division lemma to get
40 = 27 x 1 + 13
We consider the new divisor 27 and the new remainder 13,and apply the division lemma to get
27 = 13 x 2 + 1
We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 747 and 787 is 1
Notice that 1 = HCF(13,1) = HCF(27,13) = HCF(40,27) = HCF(747,40) = HCF(787,747) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 159 > 1, we apply the division lemma to 159 and 1, to get
159 = 1 x 159 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 159 is 1
Notice that 1 = HCF(159,1) .
