HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 400, 616, 556, 619 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 400, 616, 556, 619 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 400, 616, 556, 619 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 400, 616, 556, 619 is 1.
HCF(400, 616, 556, 619) = 1
HCF of 400, 616, 556, 619 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 400, 616, 556, 619 is 1.
Highest Common Factor of 400,616,556,619 is 1
Step 1: Since 616 > 400, we apply the division lemma to 616 and 400, to get
616 = 400 x 1 + 216
Step 2: Since the reminder 400 ≠ 0, we apply division lemma to 216 and 400, to get
400 = 216 x 1 + 184
Step 3: We consider the new divisor 216 and the new remainder 184, and apply the division lemma to get
216 = 184 x 1 + 32
We consider the new divisor 184 and the new remainder 32,and apply the division lemma to get
184 = 32 x 5 + 24
We consider the new divisor 32 and the new remainder 24,and apply the division lemma to get
32 = 24 x 1 + 8
We consider the new divisor 24 and the new remainder 8,and apply the division lemma to get
24 = 8 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 400 and 616 is 8
Notice that 8 = HCF(24,8) = HCF(32,24) = HCF(184,32) = HCF(216,184) = HCF(400,216) = HCF(616,400) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 556 > 8, we apply the division lemma to 556 and 8, to get
556 = 8 x 69 + 4
Step 2: Since the reminder 8 ≠ 0, we apply division lemma to 4 and 8, to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 8 and 556 is 4
Notice that 4 = HCF(8,4) = HCF(556,8) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 619 > 4, we apply the division lemma to 619 and 4, to get
619 = 4 x 154 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 619 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(619,4) .
