HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 494, 860, 220 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 494, 860, 220 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 494, 860, 220 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 494, 860, 220 is 2.
HCF(494, 860, 220) = 2
HCF of 494, 860, 220 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 494, 860, 220 is 2.
Highest Common Factor of 494,860,220 is 2
Step 1: Since 860 > 494, we apply the division lemma to 860 and 494, to get
860 = 494 x 1 + 366
Step 2: Since the reminder 494 ≠ 0, we apply division lemma to 366 and 494, to get
494 = 366 x 1 + 128
Step 3: We consider the new divisor 366 and the new remainder 128, and apply the division lemma to get
366 = 128 x 2 + 110
We consider the new divisor 128 and the new remainder 110,and apply the division lemma to get
128 = 110 x 1 + 18
We consider the new divisor 110 and the new remainder 18,and apply the division lemma to get
110 = 18 x 6 + 2
We consider the new divisor 18 and the new remainder 2,and apply the division lemma to get
18 = 2 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 494 and 860 is 2
Notice that 2 = HCF(18,2) = HCF(110,18) = HCF(128,110) = HCF(366,128) = HCF(494,366) = HCF(860,494) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 220 > 2, we apply the division lemma to 220 and 2, to get
220 = 2 x 110 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 220 is 2
Notice that 2 = HCF(220,2) .
