Given numbers are 456, 551, 945, 940
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(456, 551) = 13224
GCD(456, 551) = ( 456 x 551 ) / 13224
= 456 / 551
= 456
Step2:
LCM(19, 945) = 17955
GCD(19, 945) = ( 19 x 945 ) / 17955
= 19 / 945
= 19
Step3:
LCM(1, 940) = 940
GCD(1, 940) = ( 1 x 940 ) / 940
= 1 / 940
= 1
So, Greatest Common Divisor of 456, 551, 945, 940 is 1
