HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 922, 558, 79, 106 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 922, 558, 79, 106 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 922, 558, 79, 106 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 922, 558, 79, 106 is 1.
HCF(922, 558, 79, 106) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 922, 558, 79, 106 is 1.
Step 1: Since 922 > 558, we apply the division lemma to 922 and 558, to get
922 = 558 x 1 + 364
Step 2: Since the reminder 558 ≠ 0, we apply division lemma to 364 and 558, to get
558 = 364 x 1 + 194
Step 3: We consider the new divisor 364 and the new remainder 194, and apply the division lemma to get
364 = 194 x 1 + 170
We consider the new divisor 194 and the new remainder 170,and apply the division lemma to get
194 = 170 x 1 + 24
We consider the new divisor 170 and the new remainder 24,and apply the division lemma to get
170 = 24 x 7 + 2
We consider the new divisor 24 and the new remainder 2,and apply the division lemma to get
24 = 2 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 922 and 558 is 2
Notice that 2 = HCF(24,2) = HCF(170,24) = HCF(194,170) = HCF(364,194) = HCF(558,364) = HCF(922,558) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 79 > 2, we apply the division lemma to 79 and 2, to get
79 = 2 x 39 + 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 79 is 1
Notice that 1 = HCF(2,1) = HCF(79,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 106 > 1, we apply the division lemma to 106 and 1, to get
106 = 1 x 106 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 106 is 1
Notice that 1 = HCF(106,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
