HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1381, 9622, 66941 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1381, 9622, 66941 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 1381, 9622, 66941 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 1381, 9622, 66941 is 1.
HCF(1381, 9622, 66941) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1381, 9622, 66941 is 1.
Step 1: Since 9622 > 1381, we apply the division lemma to 9622 and 1381, to get
9622 = 1381 x 6 + 1336
Step 2: Since the reminder 1381 ≠ 0, we apply division lemma to 1336 and 1381, to get
1381 = 1336 x 1 + 45
Step 3: We consider the new divisor 1336 and the new remainder 45, and apply the division lemma to get
1336 = 45 x 29 + 31
We consider the new divisor 45 and the new remainder 31,and apply the division lemma to get
45 = 31 x 1 + 14
We consider the new divisor 31 and the new remainder 14,and apply the division lemma to get
31 = 14 x 2 + 3
We consider the new divisor 14 and the new remainder 3,and apply the division lemma to get
14 = 3 x 4 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1381 and 9622 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(31,14) = HCF(45,31) = HCF(1336,45) = HCF(1381,1336) = HCF(9622,1381) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 66941 > 1, we apply the division lemma to 66941 and 1, to get
66941 = 1 x 66941 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 66941 is 1
Notice that 1 = HCF(66941,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
