HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 222, 153, 758 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 222, 153, 758 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 222, 153, 758 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 222, 153, 758 is 1.
HCF(222, 153, 758) = 1
HCF of 222, 153, 758 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 222, 153, 758 is 1.
Highest Common Factor of 222,153,758 is 1
Step 1: Since 222 > 153, we apply the division lemma to 222 and 153, to get
222 = 153 x 1 + 69
Step 2: Since the reminder 153 ≠ 0, we apply division lemma to 69 and 153, to get
153 = 69 x 2 + 15
Step 3: We consider the new divisor 69 and the new remainder 15, and apply the division lemma to get
69 = 15 x 4 + 9
We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get
15 = 9 x 1 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 222 and 153 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(69,15) = HCF(153,69) = HCF(222,153) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 758 > 3, we apply the division lemma to 758 and 3, to get
758 = 3 x 252 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 3 and 758 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(758,3) .
