Given numbers are 620, 486, 349, 915
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 486) = 150660
GCD(620, 486) = ( 620 x 486 ) / 150660
= 620 / 486
= 620
Step2:
LCM(2, 349) = 698
GCD(2, 349) = ( 2 x 349 ) / 698
= 2 / 349
= 2
Step3:
LCM(1, 915) = 915
GCD(1, 915) = ( 1 x 915 ) / 915
= 1 / 915
= 1
So, Greatest Common Divisor of 620, 486, 349, 915 is 1
