Given numbers are 420, 675, 803, 755
The list of prime factors of all numbers are
Prime factors of 420 are 2 x 2 x 3 x 5 x 7
Prime factors of 675 are 3 x 3 x 3 x 5 x 5
Prime factors of 803 are 11 x 73
Prime factors of 755 are 5 x 151
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 420, 675, 803, 755
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 675) = 18900
GCD(420, 675) = ( 420 x 675 ) / 18900
= 420 / 675
= 420
Step2:
LCM(15, 803) = 12045
GCD(15, 803) = ( 15 x 803 ) / 12045
= 15 / 803
= 15
Step3:
LCM(1, 755) = 755
GCD(1, 755) = ( 1 x 755 ) / 755
= 1 / 755
= 1
So, Greatest Common Divisor of 420, 675, 803, 755 is 1
