HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 921, 714, 481 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 921, 714, 481 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 921, 714, 481 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 921, 714, 481 is 1.
HCF(921, 714, 481) = 1
HCF of 921, 714, 481 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 921, 714, 481 is 1.
Highest Common Factor of 921,714,481 is 1
Step 1: Since 921 > 714, we apply the division lemma to 921 and 714, to get
921 = 714 x 1 + 207
Step 2: Since the reminder 714 ≠ 0, we apply division lemma to 207 and 714, to get
714 = 207 x 3 + 93
Step 3: We consider the new divisor 207 and the new remainder 93, and apply the division lemma to get
207 = 93 x 2 + 21
We consider the new divisor 93 and the new remainder 21,and apply the division lemma to get
93 = 21 x 4 + 9
We consider the new divisor 21 and the new remainder 9,and apply the division lemma to get
21 = 9 x 2 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 921 and 714 is 3
Notice that 3 = HCF(9,3) = HCF(21,9) = HCF(93,21) = HCF(207,93) = HCF(714,207) = HCF(921,714) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 481 > 3, we apply the division lemma to 481 and 3, to get
481 = 3 x 160 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 481 is 1
Notice that 1 = HCF(3,1) = HCF(481,3) .
