HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 228, 355, 720, 94 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 228, 355, 720, 94 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 228, 355, 720, 94 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 228, 355, 720, 94 is 1.
HCF(228, 355, 720, 94) = 1
HCF of 228, 355, 720, 94 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 228, 355, 720, 94 is 1.
Highest Common Factor of 228,355,720,94 is 1
Step 1: Since 355 > 228, we apply the division lemma to 355 and 228, to get
355 = 228 x 1 + 127
Step 2: Since the reminder 228 ≠ 0, we apply division lemma to 127 and 228, to get
228 = 127 x 1 + 101
Step 3: We consider the new divisor 127 and the new remainder 101, and apply the division lemma to get
127 = 101 x 1 + 26
We consider the new divisor 101 and the new remainder 26,and apply the division lemma to get
101 = 26 x 3 + 23
We consider the new divisor 26 and the new remainder 23,and apply the division lemma to get
26 = 23 x 1 + 3
We consider the new divisor 23 and the new remainder 3,and apply the division lemma to get
23 = 3 x 7 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
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 228 and 355 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(23,3) = HCF(26,23) = HCF(101,26) = HCF(127,101) = HCF(228,127) = HCF(355,228) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 720 > 1, we apply the division lemma to 720 and 1, to get
720 = 1 x 720 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 720 is 1
Notice that 1 = HCF(720,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 94 > 1, we apply the division lemma to 94 and 1, to get
94 = 1 x 94 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 94 is 1
Notice that 1 = HCF(94,1) .
