HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 741, 454, 520 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 741, 454, 520 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 741, 454, 520 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 741, 454, 520 is 1.
HCF(741, 454, 520) = 1
HCF of 741, 454, 520 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 741, 454, 520 is 1.
Highest Common Factor of 741,454,520 is 1
Step 1: Since 741 > 454, we apply the division lemma to 741 and 454, to get
741 = 454 x 1 + 287
Step 2: Since the reminder 454 ≠ 0, we apply division lemma to 287 and 454, to get
454 = 287 x 1 + 167
Step 3: We consider the new divisor 287 and the new remainder 167, and apply the division lemma to get
287 = 167 x 1 + 120
We consider the new divisor 167 and the new remainder 120,and apply the division lemma to get
167 = 120 x 1 + 47
We consider the new divisor 120 and the new remainder 47,and apply the division lemma to get
120 = 47 x 2 + 26
We consider the new divisor 47 and the new remainder 26,and apply the division lemma to get
47 = 26 x 1 + 21
We consider the new divisor 26 and the new remainder 21,and apply the division lemma to get
26 = 21 x 1 + 5
We consider the new divisor 21 and the new remainder 5,and apply the division lemma to get
21 = 5 x 4 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 741 and 454 is 1
Notice that 1 = HCF(5,1) = HCF(21,5) = HCF(26,21) = HCF(47,26) = HCF(120,47) = HCF(167,120) = HCF(287,167) = HCF(454,287) = HCF(741,454) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 520 > 1, we apply the division lemma to 520 and 1, to get
520 = 1 x 520 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 520 is 1
Notice that 1 = HCF(520,1) .
