HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 687, 983, 11, 755 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 687, 983, 11, 755 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 687, 983, 11, 755 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 687, 983, 11, 755 is 1.
HCF(687, 983, 11, 755) = 1
HCF of 687, 983, 11, 755 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 687, 983, 11, 755 is 1.
Highest Common Factor of 687,983,11,755 is 1
Step 1: Since 983 > 687, we apply the division lemma to 983 and 687, to get
983 = 687 x 1 + 296
Step 2: Since the reminder 687 ≠ 0, we apply division lemma to 296 and 687, to get
687 = 296 x 2 + 95
Step 3: We consider the new divisor 296 and the new remainder 95, and apply the division lemma to get
296 = 95 x 3 + 11
We consider the new divisor 95 and the new remainder 11,and apply the division lemma to get
95 = 11 x 8 + 7
We consider the new divisor 11 and the new remainder 7,and apply the division lemma to get
11 = 7 x 1 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 687 and 983 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(95,11) = HCF(296,95) = HCF(687,296) = HCF(983,687) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 11 > 1, we apply the division lemma to 11 and 1, to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 11 is 1
Notice that 1 = HCF(11,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 755 > 1, we apply the division lemma to 755 and 1, to get
755 = 1 x 755 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 755 is 1
Notice that 1 = HCF(755,1) .
