HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 431, 750, 799, 87 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 431, 750, 799, 87 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 431, 750, 799, 87 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 431, 750, 799, 87 is 1.
HCF(431, 750, 799, 87) = 1
HCF of 431, 750, 799, 87 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 431, 750, 799, 87 is 1.
Highest Common Factor of 431,750,799,87 is 1
Step 1: Since 750 > 431, we apply the division lemma to 750 and 431, to get
750 = 431 x 1 + 319
Step 2: Since the reminder 431 ≠ 0, we apply division lemma to 319 and 431, to get
431 = 319 x 1 + 112
Step 3: We consider the new divisor 319 and the new remainder 112, and apply the division lemma to get
319 = 112 x 2 + 95
We consider the new divisor 112 and the new remainder 95,and apply the division lemma to get
112 = 95 x 1 + 17
We consider the new divisor 95 and the new remainder 17,and apply the division lemma to get
95 = 17 x 5 + 10
We consider the new divisor 17 and the new remainder 10,and apply the division lemma to get
17 = 10 x 1 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
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 431 and 750 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(17,10) = HCF(95,17) = HCF(112,95) = HCF(319,112) = HCF(431,319) = HCF(750,431) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 799 > 1, we apply the division lemma to 799 and 1, to get
799 = 1 x 799 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 799 is 1
Notice that 1 = HCF(799,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 87 > 1, we apply the division lemma to 87 and 1, to get
87 = 1 x 87 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 87 is 1
Notice that 1 = HCF(87,1) .
