HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 316, 730, 145 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 316, 730, 145 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 316, 730, 145 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 316, 730, 145 is 1.
HCF(316, 730, 145) = 1
HCF of 316, 730, 145 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 316, 730, 145 is 1.
Highest Common Factor of 316,730,145 is 1
Step 1: Since 730 > 316, we apply the division lemma to 730 and 316, to get
730 = 316 x 2 + 98
Step 2: Since the reminder 316 ≠ 0, we apply division lemma to 98 and 316, to get
316 = 98 x 3 + 22
Step 3: We consider the new divisor 98 and the new remainder 22, and apply the division lemma to get
98 = 22 x 4 + 10
We consider the new divisor 22 and the new remainder 10,and apply the division lemma to get
22 = 10 x 2 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 316 and 730 is 2
Notice that 2 = HCF(10,2) = HCF(22,10) = HCF(98,22) = HCF(316,98) = HCF(730,316) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 145 > 2, we apply the division lemma to 145 and 2, to get
145 = 2 x 72 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 145 is 1
Notice that 1 = HCF(2,1) = HCF(145,2) .
