Given numbers are 918, 349, 995, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(918, 349) = 320382
GCD(918, 349) = ( 918 x 349 ) / 320382
= 918 / 349
= 918
Step2:
LCM(1, 995) = 995
GCD(1, 995) = ( 1 x 995 ) / 995
= 1 / 995
= 1
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 918, 349, 995, 420 is 1
