HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 149, 714, 858 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 149, 714, 858 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 149, 714, 858 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 149, 714, 858 is 1.
HCF(149, 714, 858) = 1
HCF of 149, 714, 858 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 149, 714, 858 is 1.
Highest Common Factor of 149,714,858 is 1
Step 1: Since 714 > 149, we apply the division lemma to 714 and 149, to get
714 = 149 x 4 + 118
Step 2: Since the reminder 149 ≠ 0, we apply division lemma to 118 and 149, to get
149 = 118 x 1 + 31
Step 3: We consider the new divisor 118 and the new remainder 31, and apply the division lemma to get
118 = 31 x 3 + 25
We consider the new divisor 31 and the new remainder 25,and apply the division lemma to get
31 = 25 x 1 + 6
We consider the new divisor 25 and the new remainder 6,and apply the division lemma to get
25 = 6 x 4 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 149 and 714 is 1
Notice that 1 = HCF(6,1) = HCF(25,6) = HCF(31,25) = HCF(118,31) = HCF(149,118) = HCF(714,149) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 858 > 1, we apply the division lemma to 858 and 1, to get
858 = 1 x 858 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 858 is 1
Notice that 1 = HCF(858,1) .
