Given numbers are 755, 810, 242, 646
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(755, 810) = 122310
GCD(755, 810) = ( 755 x 810 ) / 122310
= 755 / 810
= 755
Step2:
LCM(5, 242) = 1210
GCD(5, 242) = ( 5 x 242 ) / 1210
= 5 / 242
= 5
Step3:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
So, Greatest Common Divisor of 755, 810, 242, 646 is 1
