HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 164, 922, 155, 136 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 164, 922, 155, 136 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 164, 922, 155, 136 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 164, 922, 155, 136 is 1.
HCF(164, 922, 155, 136) = 1
HCF of 164, 922, 155, 136 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 164, 922, 155, 136 is 1.
Highest Common Factor of 164,922,155,136 is 1
Step 1: Since 922 > 164, we apply the division lemma to 922 and 164, to get
922 = 164 x 5 + 102
Step 2: Since the reminder 164 ≠ 0, we apply division lemma to 102 and 164, to get
164 = 102 x 1 + 62
Step 3: We consider the new divisor 102 and the new remainder 62, and apply the division lemma to get
102 = 62 x 1 + 40
We consider the new divisor 62 and the new remainder 40,and apply the division lemma to get
62 = 40 x 1 + 22
We consider the new divisor 40 and the new remainder 22,and apply the division lemma to get
40 = 22 x 1 + 18
We consider the new divisor 22 and the new remainder 18,and apply the division lemma to get
22 = 18 x 1 + 4
We consider the new divisor 18 and the new remainder 4,and apply the division lemma to get
18 = 4 x 4 + 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 164 and 922 is 2
Notice that 2 = HCF(4,2) = HCF(18,4) = HCF(22,18) = HCF(40,22) = HCF(62,40) = HCF(102,62) = HCF(164,102) = HCF(922,164) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 155 > 2, we apply the division lemma to 155 and 2, to get
155 = 2 x 77 + 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 155 is 1
Notice that 1 = HCF(2,1) = HCF(155,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 136 > 1, we apply the division lemma to 136 and 1, to get
136 = 1 x 136 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 136 is 1
Notice that 1 = HCF(136,1) .
