Given numbers are 153, 218, 620, 369
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(153, 218) = 33354
GCD(153, 218) = ( 153 x 218 ) / 33354
= 153 / 218
= 153
Step2:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
Step3:
LCM(1, 369) = 369
GCD(1, 369) = ( 1 x 369 ) / 369
= 1 / 369
= 1
So, Greatest Common Divisor of 153, 218, 620, 369 is 1
