Prime factors of 215 are 5 x 43
Prime factors of 735 are 3 x 5 x 7 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 278, 480, 215, 735
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 480) = 66720
GCD(278, 480) = ( 278 x 480 ) / 66720
= 278 / 480
= 278
Step2:
LCM(2, 215) = 430
GCD(2, 215) = ( 2 x 215 ) / 430
= 2 / 215
= 2
Step3:
LCM(1, 735) = 735
GCD(1, 735) = ( 1 x 735 ) / 735
= 1 / 735
= 1
So, Greatest Common Divisor of 278, 480, 215, 735 is 1
