HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 605, 436, 502 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 605, 436, 502 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 605, 436, 502 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 605, 436, 502 is 1.
HCF(605, 436, 502) = 1
HCF of 605, 436, 502 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 605, 436, 502 is 1.
Highest Common Factor of 605,436,502 is 1
Step 1: Since 605 > 436, we apply the division lemma to 605 and 436, to get
605 = 436 x 1 + 169
Step 2: Since the reminder 436 ≠ 0, we apply division lemma to 169 and 436, to get
436 = 169 x 2 + 98
Step 3: We consider the new divisor 169 and the new remainder 98, and apply the division lemma to get
169 = 98 x 1 + 71
We consider the new divisor 98 and the new remainder 71,and apply the division lemma to get
98 = 71 x 1 + 27
We consider the new divisor 71 and the new remainder 27,and apply the division lemma to get
71 = 27 x 2 + 17
We consider the new divisor 27 and the new remainder 17,and apply the division lemma to get
27 = 17 x 1 + 10
We consider the new divisor 17 and the new remainder 10,and apply the division lemma to get
17 = 10 x 1 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 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 605 and 436 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(17,10) = HCF(27,17) = HCF(71,27) = HCF(98,71) = HCF(169,98) = HCF(436,169) = HCF(605,436) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 502 > 1, we apply the division lemma to 502 and 1, to get
502 = 1 x 502 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 502 is 1
Notice that 1 = HCF(502,1) .
