Given numbers are 165, 220, 354, 387
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(165, 220) = 660
GCD(165, 220) = ( 165 x 220 ) / 660
= 165 / 220
= 165
Step2:
LCM(55, 354) = 19470
GCD(55, 354) = ( 55 x 354 ) / 19470
= 55 / 354
= 55
Step3:
LCM(1, 387) = 387
GCD(1, 387) = ( 1 x 387 ) / 387
= 1 / 387
= 1
So, Greatest Common Divisor of 165, 220, 354, 387 is 1
