Given numbers are 918, 620, 617, 392
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(918, 620) = 284580
GCD(918, 620) = ( 918 x 620 ) / 284580
= 918 / 620
= 918
Step2:
LCM(2, 617) = 1234
GCD(2, 617) = ( 2 x 617 ) / 1234
= 2 / 617
= 2
Step3:
LCM(1, 392) = 392
GCD(1, 392) = ( 1 x 392 ) / 392
= 1 / 392
= 1
So, Greatest Common Divisor of 918, 620, 617, 392 is 1
