HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 147, 858 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 147, 858 is 3 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 147, 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 147, 858 is 3.
HCF(147, 858) = 3
HCF of 147, 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 147, 858 is 3.
Highest Common Factor of 147,858 is 3
Step 1: Since 858 > 147, we apply the division lemma to 858 and 147, to get
858 = 147 x 5 + 123
Step 2: Since the reminder 147 ≠ 0, we apply division lemma to 123 and 147, to get
147 = 123 x 1 + 24
Step 3: We consider the new divisor 123 and the new remainder 24, and apply the division lemma to get
123 = 24 x 5 + 3
We consider the new divisor 24 and the new remainder 3, and apply the division lemma to get
24 = 3 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 147 and 858 is 3
Notice that 3 = HCF(24,3) = HCF(123,24) = HCF(147,123) = HCF(858,147) .
