HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 402, 915, 139, 229 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 402, 915, 139, 229 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 402, 915, 139, 229 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 402, 915, 139, 229 is 1.
HCF(402, 915, 139, 229) = 1
HCF of 402, 915, 139, 229 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 402, 915, 139, 229 is 1.
Highest Common Factor of 402,915,139,229 is 1
Step 1: Since 915 > 402, we apply the division lemma to 915 and 402, to get
915 = 402 x 2 + 111
Step 2: Since the reminder 402 ≠ 0, we apply division lemma to 111 and 402, to get
402 = 111 x 3 + 69
Step 3: We consider the new divisor 111 and the new remainder 69, and apply the division lemma to get
111 = 69 x 1 + 42
We consider the new divisor 69 and the new remainder 42,and apply the division lemma to get
69 = 42 x 1 + 27
We consider the new divisor 42 and the new remainder 27,and apply the division lemma to get
42 = 27 x 1 + 15
We consider the new divisor 27 and the new remainder 15,and apply the division lemma to get
27 = 15 x 1 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 402 and 915 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(27,15) = HCF(42,27) = HCF(69,42) = HCF(111,69) = HCF(402,111) = HCF(915,402) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 139 > 3, we apply the division lemma to 139 and 3, to get
139 = 3 x 46 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 139 is 1
Notice that 1 = HCF(3,1) = HCF(139,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 229 > 1, we apply the division lemma to 229 and 1, to get
229 = 1 x 229 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 229 is 1
Notice that 1 = HCF(229,1) .
