Given numbers are 690, 624, 815, 338
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 624) = 71760
GCD(690, 624) = ( 690 x 624 ) / 71760
= 690 / 624
= 690
Step2:
LCM(6, 815) = 4890
GCD(6, 815) = ( 6 x 815 ) / 4890
= 6 / 815
= 6
Step3:
LCM(1, 338) = 338
GCD(1, 338) = ( 1 x 338 ) / 338
= 1 / 338
= 1
So, Greatest Common Divisor of 690, 624, 815, 338 is 1
