Given numbers are 646, 506, 139, 263
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 506) = 163438
GCD(646, 506) = ( 646 x 506 ) / 163438
= 646 / 506
= 646
Step2:
LCM(2, 139) = 278
GCD(2, 139) = ( 2 x 139 ) / 278
= 2 / 139
= 2
Step3:
LCM(1, 263) = 263
GCD(1, 263) = ( 1 x 263 ) / 263
= 1 / 263
= 1
So, Greatest Common Divisor of 646, 506, 139, 263 is 1
