Given numbers are 369, 280, 770, 207
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(369, 280) = 103320
GCD(369, 280) = ( 369 x 280 ) / 103320
= 369 / 280
= 369
Step2:
LCM(1, 770) = 770
GCD(1, 770) = ( 1 x 770 ) / 770
= 1 / 770
= 1
Step3:
LCM(1, 207) = 207
GCD(1, 207) = ( 1 x 207 ) / 207
= 1 / 207
= 1
So, Greatest Common Divisor of 369, 280, 770, 207 is 1
