HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 654, 357, 368 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 654, 357, 368 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 654, 357, 368 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 654, 357, 368 is 1.
HCF(654, 357, 368) = 1
HCF of 654, 357, 368 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 654, 357, 368 is 1.
Highest Common Factor of 654,357,368 is 1
Step 1: Since 654 > 357, we apply the division lemma to 654 and 357, to get
654 = 357 x 1 + 297
Step 2: Since the reminder 357 ≠ 0, we apply division lemma to 297 and 357, to get
357 = 297 x 1 + 60
Step 3: We consider the new divisor 297 and the new remainder 60, and apply the division lemma to get
297 = 60 x 4 + 57
We consider the new divisor 60 and the new remainder 57,and apply the division lemma to get
60 = 57 x 1 + 3
We consider the new divisor 57 and the new remainder 3,and apply the division lemma to get
57 = 3 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 654 and 357 is 3
Notice that 3 = HCF(57,3) = HCF(60,57) = HCF(297,60) = HCF(357,297) = HCF(654,357) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 368 > 3, we apply the division lemma to 368 and 3, to get
368 = 3 x 122 + 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 368 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(368,3) .
