HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 743, 421, 794, 901 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 743, 421, 794, 901 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 743, 421, 794, 901 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 743, 421, 794, 901 is 1.
HCF(743, 421, 794, 901) = 1
HCF of 743, 421, 794, 901 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 743, 421, 794, 901 is 1.
Highest Common Factor of 743,421,794,901 is 1
Step 1: Since 743 > 421, we apply the division lemma to 743 and 421, to get
743 = 421 x 1 + 322
Step 2: Since the reminder 421 ≠ 0, we apply division lemma to 322 and 421, to get
421 = 322 x 1 + 99
Step 3: We consider the new divisor 322 and the new remainder 99, and apply the division lemma to get
322 = 99 x 3 + 25
We consider the new divisor 99 and the new remainder 25,and apply the division lemma to get
99 = 25 x 3 + 24
We consider the new divisor 25 and the new remainder 24,and apply the division lemma to get
25 = 24 x 1 + 1
We consider the new divisor 24 and the new remainder 1,and apply the division lemma to get
24 = 1 x 24 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 743 and 421 is 1
Notice that 1 = HCF(24,1) = HCF(25,24) = HCF(99,25) = HCF(322,99) = HCF(421,322) = HCF(743,421) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 794 > 1, we apply the division lemma to 794 and 1, to get
794 = 1 x 794 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 794 is 1
Notice that 1 = HCF(794,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 901 > 1, we apply the division lemma to 901 and 1, to get
901 = 1 x 901 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 901 is 1
Notice that 1 = HCF(901,1) .
