HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 858, 530, 500 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 858, 530, 500 is 2 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 858, 530, 500 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 858, 530, 500 is 2.
HCF(858, 530, 500) = 2
HCF of 858, 530, 500 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 858, 530, 500 is 2.
Highest Common Factor of 858,530,500 is 2
Step 1: Since 858 > 530, we apply the division lemma to 858 and 530, to get
858 = 530 x 1 + 328
Step 2: Since the reminder 530 ≠ 0, we apply division lemma to 328 and 530, to get
530 = 328 x 1 + 202
Step 3: We consider the new divisor 328 and the new remainder 202, and apply the division lemma to get
328 = 202 x 1 + 126
We consider the new divisor 202 and the new remainder 126,and apply the division lemma to get
202 = 126 x 1 + 76
We consider the new divisor 126 and the new remainder 76,and apply the division lemma to get
126 = 76 x 1 + 50
We consider the new divisor 76 and the new remainder 50,and apply the division lemma to get
76 = 50 x 1 + 26
We consider the new divisor 50 and the new remainder 26,and apply the division lemma to get
50 = 26 x 1 + 24
We consider the new divisor 26 and the new remainder 24,and apply the division lemma to get
26 = 24 x 1 + 2
We consider the new divisor 24 and the new remainder 2,and apply the division lemma to get
24 = 2 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 858 and 530 is 2
Notice that 2 = HCF(24,2) = HCF(26,24) = HCF(50,26) = HCF(76,50) = HCF(126,76) = HCF(202,126) = HCF(328,202) = HCF(530,328) = HCF(858,530) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 500 > 2, we apply the division lemma to 500 and 2, to get
500 = 2 x 250 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 500 is 2
Notice that 2 = HCF(500,2) .
