HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 494, 136, 242, 877 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 494, 136, 242, 877 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 494, 136, 242, 877 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, 136, 242, 877 is 1.
HCF(494, 136, 242, 877) = 1
HCF of 494, 136, 242, 877 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, 136, 242, 877 is 1.
Highest Common Factor of 494,136,242,877 is 1
Step 1: Since 494 > 136, we apply the division lemma to 494 and 136, to get
494 = 136 x 3 + 86
Step 2: Since the reminder 136 ≠ 0, we apply division lemma to 86 and 136, to get
136 = 86 x 1 + 50
Step 3: We consider the new divisor 86 and the new remainder 50, and apply the division lemma to get
86 = 50 x 1 + 36
We consider the new divisor 50 and the new remainder 36,and apply the division lemma to get
50 = 36 x 1 + 14
We consider the new divisor 36 and the new remainder 14,and apply the division lemma to get
36 = 14 x 2 + 8
We consider the new divisor 14 and the new remainder 8,and apply the division lemma to get
14 = 8 x 1 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 494 and 136 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(14,8) = HCF(36,14) = HCF(50,36) = HCF(86,50) = HCF(136,86) = HCF(494,136) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 242 > 2, we apply the division lemma to 242 and 2, to get
242 = 2 x 121 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 242 is 2
Notice that 2 = HCF(242,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 877 > 2, we apply the division lemma to 877 and 2, to get
877 = 2 x 438 + 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 877 is 1
Notice that 1 = HCF(2,1) = HCF(877,2) .
