Given numbers are 757, 155, 475, 309
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(757, 155) = 117335
GCD(757, 155) = ( 757 x 155 ) / 117335
= 757 / 155
= 757
Step2:
LCM(1, 475) = 475
GCD(1, 475) = ( 1 x 475 ) / 475
= 1 / 475
= 1
Step3:
LCM(1, 309) = 309
GCD(1, 309) = ( 1 x 309 ) / 309
= 1 / 309
= 1
So, Greatest Common Divisor of 757, 155, 475, 309 is 1
