HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 242, 560, 827 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 870, 242, 560, 827 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 870, 242, 560, 827 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, 242, 560, 827 is 1.
HCF(870, 242, 560, 827) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 870, 242, 560, 827 is 1.
Step 1: Since 870 > 242, we apply the division lemma to 870 and 242, to get
870 = 242 x 3 + 144
Step 2: Since the reminder 242 ≠ 0, we apply division lemma to 144 and 242, to get
242 = 144 x 1 + 98
Step 3: We consider the new divisor 144 and the new remainder 98, and apply the division lemma to get
144 = 98 x 1 + 46
We consider the new divisor 98 and the new remainder 46,and apply the division lemma to get
98 = 46 x 2 + 6
We consider the new divisor 46 and the new remainder 6,and apply the division lemma to get
46 = 6 x 7 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 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 242 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(46,6) = HCF(98,46) = HCF(144,98) = HCF(242,144) = HCF(870,242) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 560 > 2, we apply the division lemma to 560 and 2, to get
560 = 2 x 280 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 560 is 2
Notice that 2 = HCF(560,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 827 > 2, we apply the division lemma to 827 and 2, to get
827 = 2 x 413 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 827 is 1
Notice that 1 = HCF(2,1) = HCF(827,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
