HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 640, 2842 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 640, 2842 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 640, 2842 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 640, 2842 is 2.
HCF(640, 2842) = 2
HCF of 640, 2842 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 640, 2842 is 2.
Highest Common Factor of 640,2842 is 2
Step 1: Since 2842 > 640, we apply the division lemma to 2842 and 640, to get
2842 = 640 x 4 + 282
Step 2: Since the reminder 640 ≠ 0, we apply division lemma to 282 and 640, to get
640 = 282 x 2 + 76
Step 3: We consider the new divisor 282 and the new remainder 76, and apply the division lemma to get
282 = 76 x 3 + 54
We consider the new divisor 76 and the new remainder 54,and apply the division lemma to get
76 = 54 x 1 + 22
We consider the new divisor 54 and the new remainder 22,and apply the division lemma to get
54 = 22 x 2 + 10
We consider the new divisor 22 and the new remainder 10,and apply the division lemma to get
22 = 10 x 2 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 640 and 2842 is 2
Notice that 2 = HCF(10,2) = HCF(22,10) = HCF(54,22) = HCF(76,54) = HCF(282,76) = HCF(640,282) = HCF(2842,640) .
