Given numbers are 460, 210, 655, 387
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(460, 210) = 9660
GCD(460, 210) = ( 460 x 210 ) / 9660
= 460 / 210
= 460
Step2:
LCM(10, 655) = 1310
GCD(10, 655) = ( 10 x 655 ) / 1310
= 10 / 655
= 10
Step3:
LCM(5, 387) = 1935
GCD(5, 387) = ( 5 x 387 ) / 1935
= 5 / 387
= 5
So, Greatest Common Divisor of 460, 210, 655, 387 is 1
