HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 585, 151, 861, 715 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 585, 151, 861, 715 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 585, 151, 861, 715 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 585, 151, 861, 715 is 1.
HCF(585, 151, 861, 715) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 585, 151, 861, 715 is 1.
Step 1: Since 585 > 151, we apply the division lemma to 585 and 151, to get
585 = 151 x 3 + 132
Step 2: Since the reminder 151 ≠ 0, we apply division lemma to 132 and 151, to get
151 = 132 x 1 + 19
Step 3: We consider the new divisor 132 and the new remainder 19, and apply the division lemma to get
132 = 19 x 6 + 18
We consider the new divisor 19 and the new remainder 18,and apply the division lemma to get
19 = 18 x 1 + 1
We consider the new divisor 18 and the new remainder 1,and apply the division lemma to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 585 and 151 is 1
Notice that 1 = HCF(18,1) = HCF(19,18) = HCF(132,19) = HCF(151,132) = HCF(585,151) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 861 > 1, we apply the division lemma to 861 and 1, to get
861 = 1 x 861 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 861 is 1
Notice that 1 = HCF(861,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 715 > 1, we apply the division lemma to 715 and 1, to get
715 = 1 x 715 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 715 is 1
Notice that 1 = HCF(715,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
