Given numbers are 278, 623, 478, 635
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 623) = 173194
GCD(278, 623) = ( 278 x 623 ) / 173194
= 278 / 623
= 278
Step2:
LCM(1, 478) = 478
GCD(1, 478) = ( 1 x 478 ) / 478
= 1 / 478
= 1
Step3:
LCM(1, 635) = 635
GCD(1, 635) = ( 1 x 635 ) / 635
= 1 / 635
= 1
So, Greatest Common Divisor of 278, 623, 478, 635 is 1
