Given numbers are 790, 248, 647, 169
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(790, 248) = 97960
GCD(790, 248) = ( 790 x 248 ) / 97960
= 790 / 248
= 790
Step2:
LCM(2, 647) = 1294
GCD(2, 647) = ( 2 x 647 ) / 1294
= 2 / 647
= 2
Step3:
LCM(1, 169) = 169
GCD(1, 169) = ( 1 x 169 ) / 169
= 1 / 169
= 1
So, Greatest Common Divisor of 790, 248, 647, 169 is 1
