Given numbers are 434, 781, 757, 478
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(434, 781) = 338954
GCD(434, 781) = ( 434 x 781 ) / 338954
= 434 / 781
= 434
Step2:
LCM(1, 757) = 757
GCD(1, 757) = ( 1 x 757 ) / 757
= 1 / 757
= 1
Step3:
LCM(1, 478) = 478
GCD(1, 478) = ( 1 x 478 ) / 478
= 1 / 478
= 1
So, Greatest Common Divisor of 434, 781, 757, 478 is 1
