HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 135, 976, 729, 381 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 135, 976, 729, 381 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 135, 976, 729, 381 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 135, 976, 729, 381 is 1.
HCF(135, 976, 729, 381) = 1
HCF of 135, 976, 729, 381 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 135, 976, 729, 381 is 1.
Highest Common Factor of 135,976,729,381 is 1
Step 1: Since 976 > 135, we apply the division lemma to 976 and 135, to get
976 = 135 x 7 + 31
Step 2: Since the reminder 135 ≠ 0, we apply division lemma to 31 and 135, to get
135 = 31 x 4 + 11
Step 3: We consider the new divisor 31 and the new remainder 11, and apply the division lemma to get
31 = 11 x 2 + 9
We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get
11 = 9 x 1 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 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 135 and 976 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(31,11) = HCF(135,31) = HCF(976,135) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 729 > 1, we apply the division lemma to 729 and 1, to get
729 = 1 x 729 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 729 is 1
Notice that 1 = HCF(729,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 381 > 1, we apply the division lemma to 381 and 1, to get
381 = 1 x 381 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 381 is 1
Notice that 1 = HCF(381,1) .
