HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 152, 281, 390 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 152, 281, 390 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 152, 281, 390 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 152, 281, 390 is 1.
HCF(152, 281, 390) = 1
HCF of 152, 281, 390 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 152, 281, 390 is 1.
Highest Common Factor of 152,281,390 is 1
Step 1: Since 281 > 152, we apply the division lemma to 281 and 152, to get
281 = 152 x 1 + 129
Step 2: Since the reminder 152 ≠ 0, we apply division lemma to 129 and 152, to get
152 = 129 x 1 + 23
Step 3: We consider the new divisor 129 and the new remainder 23, and apply the division lemma to get
129 = 23 x 5 + 14
We consider the new divisor 23 and the new remainder 14,and apply the division lemma to get
23 = 14 x 1 + 9
We consider the new divisor 14 and the new remainder 9,and apply the division lemma to get
14 = 9 x 1 + 5
We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get
9 = 5 x 1 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 152 and 281 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(14,9) = HCF(23,14) = HCF(129,23) = HCF(152,129) = HCF(281,152) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 390 > 1, we apply the division lemma to 390 and 1, to get
390 = 1 x 390 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 390 is 1
Notice that 1 = HCF(390,1) .
