Given numbers are 240, 742, 505, 396
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(240, 742) = 89040
GCD(240, 742) = ( 240 x 742 ) / 89040
= 240 / 742
= 240
Step2:
LCM(2, 505) = 1010
GCD(2, 505) = ( 2 x 505 ) / 1010
= 2 / 505
= 2
Step3:
LCM(1, 396) = 396
GCD(1, 396) = ( 1 x 396 ) / 396
= 1 / 396
= 1
So, Greatest Common Divisor of 240, 742, 505, 396 is 1
