Given numbers are 456, 147, 747, 455
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(456, 147) = 22344
GCD(456, 147) = ( 456 x 147 ) / 22344
= 456 / 147
= 456
Step2:
LCM(3, 747) = 747
GCD(3, 747) = ( 3 x 747 ) / 747
= 3 / 747
= 3
Step3:
LCM(3, 455) = 1365
GCD(3, 455) = ( 3 x 455 ) / 1365
= 3 / 455
= 3
So, Greatest Common Divisor of 456, 147, 747, 455 is 1
