Given numbers are 643, 278, 88, 251
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 278) = 178754
GCD(643, 278) = ( 643 x 278 ) / 178754
= 643 / 278
= 643
Step2:
LCM(1, 88) = 88
GCD(1, 88) = ( 1 x 88 ) / 88
= 1 / 88
= 1
Step3:
LCM(1, 251) = 251
GCD(1, 251) = ( 1 x 251 ) / 251
= 1 / 251
= 1
So, Greatest Common Divisor of 643, 278, 88, 251 is 1
