Given numbers are 390, 253, 207, 201
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 253) = 98670
GCD(390, 253) = ( 390 x 253 ) / 98670
= 390 / 253
= 390
Step2:
LCM(1, 207) = 207
GCD(1, 207) = ( 1 x 207 ) / 207
= 1 / 207
= 1
Step3:
LCM(1, 201) = 201
GCD(1, 201) = ( 1 x 201 ) / 201
= 1 / 201
= 1
So, Greatest Common Divisor of 390, 253, 207, 201 is 1
