HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 150, 257, 205, 749 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 150, 257, 205, 749 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 150, 257, 205, 749 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 150, 257, 205, 749 is 1.
HCF(150, 257, 205, 749) = 1
HCF of 150, 257, 205, 749 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 150, 257, 205, 749 is 1.
Highest Common Factor of 150,257,205,749 is 1
Step 1: Since 257 > 150, we apply the division lemma to 257 and 150, to get
257 = 150 x 1 + 107
Step 2: Since the reminder 150 ≠ 0, we apply division lemma to 107 and 150, to get
150 = 107 x 1 + 43
Step 3: We consider the new divisor 107 and the new remainder 43, and apply the division lemma to get
107 = 43 x 2 + 21
We consider the new divisor 43 and the new remainder 21,and apply the division lemma to get
43 = 21 x 2 + 1
We consider the new divisor 21 and the new remainder 1,and apply the division lemma to get
21 = 1 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 150 and 257 is 1
Notice that 1 = HCF(21,1) = HCF(43,21) = HCF(107,43) = HCF(150,107) = HCF(257,150) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 205 > 1, we apply the division lemma to 205 and 1, to get
205 = 1 x 205 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 205 is 1
Notice that 1 = HCF(205,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 749 > 1, we apply the division lemma to 749 and 1, to get
749 = 1 x 749 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 749 is 1
Notice that 1 = HCF(749,1) .
