HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 120, 425, 358, 392 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 120, 425, 358, 392 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 120, 425, 358, 392 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 120, 425, 358, 392 is 1.
HCF(120, 425, 358, 392) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 120, 425, 358, 392 is 1.
Step 1: Since 425 > 120, we apply the division lemma to 425 and 120, to get
425 = 120 x 3 + 65
Step 2: Since the reminder 120 ≠ 0, we apply division lemma to 65 and 120, to get
120 = 65 x 1 + 55
Step 3: We consider the new divisor 65 and the new remainder 55, and apply the division lemma to get
65 = 55 x 1 + 10
We consider the new divisor 55 and the new remainder 10,and apply the division lemma to get
55 = 10 x 5 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 120 and 425 is 5
Notice that 5 = HCF(10,5) = HCF(55,10) = HCF(65,55) = HCF(120,65) = HCF(425,120) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 358 > 5, we apply the division lemma to 358 and 5, to get
358 = 5 x 71 + 3
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get
5 = 3 x 1 + 2
Step 3: 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 5 and 358 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(358,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 392 > 1, we apply the division lemma to 392 and 1, to get
392 = 1 x 392 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 392 is 1
Notice that 1 = HCF(392,1) .
