Given numbers are 665, 670, 616, 855
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(665, 670) = 89110
GCD(665, 670) = ( 665 x 670 ) / 89110
= 665 / 670
= 665
Step2:
LCM(5, 616) = 3080
GCD(5, 616) = ( 5 x 616 ) / 3080
= 5 / 616
= 5
Step3:
LCM(1, 855) = 855
GCD(1, 855) = ( 1 x 855 ) / 855
= 1 / 855
= 1
So, Greatest Common Divisor of 665, 670, 616, 855 is 1
