HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 929, 728, 357 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 929, 728, 357 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 929, 728, 357 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 929, 728, 357 is 1.
HCF(929, 728, 357) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 929, 728, 357 is 1.
Step 1: Since 929 > 728, we apply the division lemma to 929 and 728, to get
929 = 728 x 1 + 201
Step 2: Since the reminder 728 ≠ 0, we apply division lemma to 201 and 728, to get
728 = 201 x 3 + 125
Step 3: We consider the new divisor 201 and the new remainder 125, and apply the division lemma to get
201 = 125 x 1 + 76
We consider the new divisor 125 and the new remainder 76,and apply the division lemma to get
125 = 76 x 1 + 49
We consider the new divisor 76 and the new remainder 49,and apply the division lemma to get
76 = 49 x 1 + 27
We consider the new divisor 49 and the new remainder 27,and apply the division lemma to get
49 = 27 x 1 + 22
We consider the new divisor 27 and the new remainder 22,and apply the division lemma to get
27 = 22 x 1 + 5
We consider the new divisor 22 and the new remainder 5,and apply the division lemma to get
22 = 5 x 4 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 929 and 728 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(22,5) = HCF(27,22) = HCF(49,27) = HCF(76,49) = HCF(125,76) = HCF(201,125) = HCF(728,201) = HCF(929,728) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 357 > 1, we apply the division lemma to 357 and 1, to get
357 = 1 x 357 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 357 is 1
Notice that 1 = HCF(357,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
