HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 143, 949, 738, 683 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 143, 949, 738, 683 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 143, 949, 738, 683 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 143, 949, 738, 683 is 1.
HCF(143, 949, 738, 683) = 1
HCF of 143, 949, 738, 683 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 143, 949, 738, 683 is 1.
Highest Common Factor of 143,949,738,683 is 1
Step 1: Since 949 > 143, we apply the division lemma to 949 and 143, to get
949 = 143 x 6 + 91
Step 2: Since the reminder 143 ≠ 0, we apply division lemma to 91 and 143, to get
143 = 91 x 1 + 52
Step 3: We consider the new divisor 91 and the new remainder 52, and apply the division lemma to get
91 = 52 x 1 + 39
We consider the new divisor 52 and the new remainder 39,and apply the division lemma to get
52 = 39 x 1 + 13
We consider the new divisor 39 and the new remainder 13,and apply the division lemma to get
39 = 13 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 143 and 949 is 13
Notice that 13 = HCF(39,13) = HCF(52,39) = HCF(91,52) = HCF(143,91) = HCF(949,143) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 738 > 13, we apply the division lemma to 738 and 13, to get
738 = 13 x 56 + 10
Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 10 and 13, to get
13 = 10 x 1 + 3
Step 3: We consider the new divisor 10 and the new remainder 3, and apply the division lemma to get
10 = 3 x 3 + 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 13 and 738 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(738,13) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 683 > 1, we apply the division lemma to 683 and 1, to get
683 = 1 x 683 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 683 is 1
Notice that 1 = HCF(683,1) .
