Given numbers are 918, 698, 555, 646
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(918, 698) = 320382
GCD(918, 698) = ( 918 x 698 ) / 320382
= 918 / 698
= 918
Step2:
LCM(2, 555) = 1110
GCD(2, 555) = ( 2 x 555 ) / 1110
= 2 / 555
= 2
Step3:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
So, Greatest Common Divisor of 918, 698, 555, 646 is 1
