Given numbers are 886, 147, 438, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(886, 147) = 130242
GCD(886, 147) = ( 886 x 147 ) / 130242
= 886 / 147
= 886
Step2:
LCM(1, 438) = 438
GCD(1, 438) = ( 1 x 438 ) / 438
= 1 / 438
= 1
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 886, 147, 438, 781 is 1
