HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 188, 218, 850 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 870, 188, 218, 850 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 870, 188, 218, 850 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 870, 188, 218, 850 is 2.
HCF(870, 188, 218, 850) = 2
HCF of 870, 188, 218, 850 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 870, 188, 218, 850 is 2.
Highest Common Factor of 870,188,218,850 is 2
Step 1: Since 870 > 188, we apply the division lemma to 870 and 188, to get
870 = 188 x 4 + 118
Step 2: Since the reminder 188 ≠ 0, we apply division lemma to 118 and 188, to get
188 = 118 x 1 + 70
Step 3: We consider the new divisor 118 and the new remainder 70, and apply the division lemma to get
118 = 70 x 1 + 48
We consider the new divisor 70 and the new remainder 48,and apply the division lemma to get
70 = 48 x 1 + 22
We consider the new divisor 48 and the new remainder 22,and apply the division lemma to get
48 = 22 x 2 + 4
We consider the new divisor 22 and the new remainder 4,and apply the division lemma to get
22 = 4 x 5 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 870 and 188 is 2
Notice that 2 = HCF(4,2) = HCF(22,4) = HCF(48,22) = HCF(70,48) = HCF(118,70) = HCF(188,118) = HCF(870,188) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 218 > 2, we apply the division lemma to 218 and 2, to get
218 = 2 x 109 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 218 is 2
Notice that 2 = HCF(218,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 850 > 2, we apply the division lemma to 850 and 2, to get
850 = 2 x 425 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 850 is 2
Notice that 2 = HCF(850,2) .
