HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 494, 365, 145, 679 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 494, 365, 145, 679 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 494, 365, 145, 679 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 494, 365, 145, 679 is 1.
HCF(494, 365, 145, 679) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 494, 365, 145, 679 is 1.
Step 1: Since 494 > 365, we apply the division lemma to 494 and 365, to get
494 = 365 x 1 + 129
Step 2: Since the reminder 365 ≠ 0, we apply division lemma to 129 and 365, to get
365 = 129 x 2 + 107
Step 3: We consider the new divisor 129 and the new remainder 107, and apply the division lemma to get
129 = 107 x 1 + 22
We consider the new divisor 107 and the new remainder 22,and apply the division lemma to get
107 = 22 x 4 + 19
We consider the new divisor 22 and the new remainder 19,and apply the division lemma to get
22 = 19 x 1 + 3
We consider the new divisor 19 and the new remainder 3,and apply the division lemma to get
19 = 3 x 6 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 494 and 365 is 1
Notice that 1 = HCF(3,1) = HCF(19,3) = HCF(22,19) = HCF(107,22) = HCF(129,107) = HCF(365,129) = HCF(494,365) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 145 > 1, we apply the division lemma to 145 and 1, to get
145 = 1 x 145 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 145 is 1
Notice that 1 = HCF(145,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 679 > 1, we apply the division lemma to 679 and 1, to get
679 = 1 x 679 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 679 is 1
Notice that 1 = HCF(679,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
