Given numbers are 690, 566, 398, 725
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 566) = 195270
GCD(690, 566) = ( 690 x 566 ) / 195270
= 690 / 566
= 690
Step2:
LCM(2, 398) = 398
GCD(2, 398) = ( 2 x 398 ) / 398
= 2 / 398
= 2
Step3:
LCM(2, 725) = 1450
GCD(2, 725) = ( 2 x 725 ) / 1450
= 2 / 725
= 2
So, Greatest Common Divisor of 690, 566, 398, 725 is 1
