HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 158, 790, 860 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 158, 790, 860 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 158, 790, 860 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 158, 790, 860 is 2.
HCF(158, 790, 860) = 2
HCF of 158, 790, 860 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 158, 790, 860 is 2.
Highest Common Factor of 158,790,860 is 2
Step 1: Since 790 > 158, we apply the division lemma to 790 and 158, to get
790 = 158 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 158, the HCF of 158 and 790 is 158
Notice that 158 = HCF(790,158) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 860 > 158, we apply the division lemma to 860 and 158, to get
860 = 158 x 5 + 70
Step 2: Since the reminder 158 ≠ 0, we apply division lemma to 70 and 158, to get
158 = 70 x 2 + 18
Step 3: We consider the new divisor 70 and the new remainder 18, and apply the division lemma to get
70 = 18 x 3 + 16
We consider the new divisor 18 and the new remainder 16,and apply the division lemma to get
18 = 16 x 1 + 2
We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 158 and 860 is 2
Notice that 2 = HCF(16,2) = HCF(18,16) = HCF(70,18) = HCF(158,70) = HCF(860,158) .
