Given numbers are 880, 660, 387, 396
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(880, 660) = 2640
GCD(880, 660) = ( 880 x 660 ) / 2640
= 880 / 660
= 880
Step2:
LCM(220, 387) = 85140
GCD(220, 387) = ( 220 x 387 ) / 85140
= 220 / 387
= 220
Step3:
LCM(1, 396) = 396
GCD(1, 396) = ( 1 x 396 ) / 396
= 1 / 396
= 1
So, Greatest Common Divisor of 880, 660, 387, 396 is 1
