Given numbers are 399, 570, 440, 698
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(399, 570) = 3990
GCD(399, 570) = ( 399 x 570 ) / 3990
= 399 / 570
= 399
Step2:
LCM(57, 440) = 25080
GCD(57, 440) = ( 57 x 440 ) / 25080
= 57 / 440
= 57
Step3:
LCM(1, 698) = 698
GCD(1, 698) = ( 1 x 698 ) / 698
= 1 / 698
= 1
So, Greatest Common Divisor of 399, 570, 440, 698 is 1
