Given numbers are 240, 728, 605, 436
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(240, 728) = 21840
GCD(240, 728) = ( 240 x 728 ) / 21840
= 240 / 728
= 240
Step2:
LCM(8, 605) = 4840
GCD(8, 605) = ( 8 x 605 ) / 4840
= 8 / 605
= 8
Step3:
LCM(1, 436) = 436
GCD(1, 436) = ( 1 x 436 ) / 436
= 1 / 436
= 1
So, Greatest Common Divisor of 240, 728, 605, 436 is 1
