Given numbers are 356, 716, 628, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(356, 716) = 63724
GCD(356, 716) = ( 356 x 716 ) / 63724
= 356 / 716
= 356
Step2:
LCM(4, 628) = 628
GCD(4, 628) = ( 4 x 628 ) / 628
= 4 / 628
= 4
Step3:
LCM(4, 781) = 3124
GCD(4, 781) = ( 4 x 781 ) / 3124
= 4 / 781
= 4
So, Greatest Common Divisor of 356, 716, 628, 781 is 1
