Given numbers are 175, 155, 288, 664
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(175, 155) = 5425
GCD(175, 155) = ( 175 x 155 ) / 5425
= 175 / 155
= 175
Step2:
LCM(5, 288) = 1440
GCD(5, 288) = ( 5 x 288 ) / 1440
= 5 / 288
= 5
Step3:
LCM(1, 664) = 664
GCD(1, 664) = ( 1 x 664 ) / 664
= 1 / 664
= 1
So, Greatest Common Divisor of 175, 155, 288, 664 is 1
