HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 840, 983, 536 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 840, 983, 536 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 840, 983, 536 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 840, 983, 536 is 1.
HCF(840, 983, 536) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 840, 983, 536 is 1.
Step 1: Since 983 > 840, we apply the division lemma to 983 and 840, to get
983 = 840 x 1 + 143
Step 2: Since the reminder 840 ≠ 0, we apply division lemma to 143 and 840, to get
840 = 143 x 5 + 125
Step 3: We consider the new divisor 143 and the new remainder 125, and apply the division lemma to get
143 = 125 x 1 + 18
We consider the new divisor 125 and the new remainder 18,and apply the division lemma to get
125 = 18 x 6 + 17
We consider the new divisor 18 and the new remainder 17,and apply the division lemma to get
18 = 17 x 1 + 1
We consider the new divisor 17 and the new remainder 1,and apply the division lemma to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 840 and 983 is 1
Notice that 1 = HCF(17,1) = HCF(18,17) = HCF(125,18) = HCF(143,125) = HCF(840,143) = HCF(983,840) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 536 > 1, we apply the division lemma to 536 and 1, to get
536 = 1 x 536 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 536 is 1
Notice that 1 = HCF(536,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
