Given numbers are 770, 300, 448, 405
The list of prime factors of all numbers are
Prime factors of 770 are 2 x 5 x 7 x 11
Prime factors of 300 are 2 x 2 x 3 x 5 x 5
Prime factors of 448 are 2 x 2 x 2 x 2 x 2 x 2 x 7
Prime factors of 405 are 3 x 3 x 3 x 3 x 5
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 770, 300, 448, 405
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(770, 300) = 23100
GCD(770, 300) = ( 770 x 300 ) / 23100
= 770 / 300
= 770
Step2:
LCM(10, 448) = 2240
GCD(10, 448) = ( 10 x 448 ) / 2240
= 10 / 448
= 10
Step3:
LCM(2, 405) = 810
GCD(2, 405) = ( 2 x 405 ) / 810
= 2 / 405
= 2
So, Greatest Common Divisor of 770, 300, 448, 405 is 1
