Given numbers are 418, 690, 487, 704
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(418, 690) = 144210
GCD(418, 690) = ( 418 x 690 ) / 144210
= 418 / 690
= 418
Step2:
LCM(2, 487) = 974
GCD(2, 487) = ( 2 x 487 ) / 974
= 2 / 487
= 2
Step3:
LCM(1, 704) = 704
GCD(1, 704) = ( 1 x 704 ) / 704
= 1 / 704
= 1
So, Greatest Common Divisor of 418, 690, 487, 704 is 1
