Given numbers are 690, 725, 780, 359
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 725) = 100050
GCD(690, 725) = ( 690 x 725 ) / 100050
= 690 / 725
= 690
Step2:
LCM(5, 780) = 780
GCD(5, 780) = ( 5 x 780 ) / 780
= 5 / 780
= 5
Step3:
LCM(5, 359) = 1795
GCD(5, 359) = ( 5 x 359 ) / 1795
= 5 / 359
= 5
So, Greatest Common Divisor of 690, 725, 780, 359 is 1
